Precisely because of the size of the molecules. Larger molecules have a greater tendency to stick together, because there are more places where they can interact, and thus, a greater total force.

For a standard household incandescent it is 200w.

Mogul incandescents can reach 3-500w depending.

Halogen tubes typically reach 500w.

Sodium-halide , high pressure sodium , Mercury vapor , and Arc lamps can reach into the thousands of watts but are not usually used in a household setting.

It should turn off.

A switch is fitted to turn off the light whilst the door is closed to avoid wasting money on electricity. It would be wasted in two ways: you don't need the light to be on - you're not in there reading a book or anything - and the milk and salad don't need the light on to stop them having nightmares, but, if it is on, it's using electricity. Also - don't forget this point - the heat from the light has to be pumped away from the inside of the fridge by its compressor pump and having to do that wastes even more electricity!

OK, the amount of electricity may seem small - the lamp may only take 25 Watts but the compressor would have to take more than that amount of power because it cannot be 100% efficient at pumping heat. Compressor pumps are only about 67% efficient, so the compressor would have to use 25/0.67 = 37.3, let's say 37 Watts to remove the lamp's 25 watts of heat. So, if there was no door switch to turn off the light, your fridge would draw 25+37= 62 Watts every hour, 24/7. Thus in a year it would use 62x24x7x52 = 541,632 Watt-hours or about 542 kiloWatt-hours (kW-h). At 20 cents per kW-h, running that lamp would cost a cool US $108 Dollars a year just for the extra electricity!

So, if your fridge light doesn't turn off, you'll need to either fix that door switch or, if you have to pay someone to do it, it might even be a better deal to invest in a new fridge! Another solution - but you may not like the result if you do this - is simply to remove the light bulb...

Alternating Current (AC), which means it changes from positive to negative at a frequency of 50 or 60 cycles per second. In USA, Canada and other countries which use similar standards for mains electricity supply, the voltage coming into the house is usually an average of 240 Volts AC. This is split into two, with a common neutral wire, so that 120 Volts AC is the voltage supplied from most ordinary socket outlets. Some high powered appliances, such as kitchen stoves or ranges, water heaters and dryers, run at the full 240 Volts. In Europe and many other countries the alternating current changes from positive to negative at a frequency of 50 cycles per second. The voltage coming into the house is usually an average of 230 Volts AC and that is what is supplied from most ordinary socket outlets. As in the US system, high powered appliances, such as kitchen stoves or ranges, water heaters and dryers, also run at 230 Volts.

Converting CFH to CCF is hard, and there are several online converters to improve this operation. However, the general rule of thumb for conversion is: 1 Therms (u's) to Cubic Feet Of Natural Gas = 99.9761.

Crude oil has a strong, pungent odor that is often described as a mix of gasoline and tar. It can be particularly overpowering in its raw form.

Ripley says it's 10 million tons but I don't believe it.

Depending on what state you live in the power company will provide assistance thourgh its different charites. There are many non profit agency that will provide assitance in paying your electric bill.

Crude oil is formed from the remains of ancient organic matter, primarily composed of carbon-based compounds such as hydrocarbons. Over millions of years, these organic materials are subjected to heat and pressure, transforming into crude oil. Carbon atoms are essential elements in the formation of hydrocarbons that make up crude oil.

Power stations use the heat from burning fuel or splitting atoms to produce steam. This steam then drives a turbine connected to a generator, which produces electricity by spinning coils within a magnetic field. The movement of the coils generates an electrical current which is then sent out to the power grid.

In a nuclear power plant, the energy transformation involves converting nuclear energy from the fission process into heat. This heat is then used to produce steam, which drives a turbine connected to a generator. The generator then converts the mechanical energy from the turbine into electrical energy.

This is a question of overall energy policy, the federal government should have some influence on this, and it is connected to efforts to reduce fossil fuel use. My own view (as a non-US person) is that it would be sensible to plan to replace old stations as they come to the end of life, but that a significant expansion of nuclear power should be dependent on agreeing and starting to implement a route for permanent storage of high level waste, ie spent fuel, which is still being stored on power plant sites. It would also be important to ensure the NRC has adequate resources to monitor the new plants. I don't think we should. There is a possibility of a plant exploding and would cause great devastation in an area about the size of Pennsylvania. Also we do not have and efficient way to get rid of the nuclear waste. I heard this from my chemistry teacher. Actually Nuclear Energy is much more efficient than coal. The problem right now would be that the nuclear "waste" is being stored in underground bunkers somewhere in the Rockies, but this waste is actually still active enough that we could re-use it.

No methane does not conduct electricity in any form. Methane is a covalent molecule and does not break into ions (which are responsible to conduct the electricity between two electrodes) so methane is non conductor.

Water companies typically calculate domestic water bills based on a combination of fixed charges (such as meter fees) and variable charges (based on the amount of water used, measured in cubic meters or gallons). The formula usually involves multiplying the water usage by a rate set by the company to determine the cost. Additional charges may apply for services like sewage treatment.

Load shedding is the deliberate shutdown of electric power in a part or parts of an electricity distribution system, usually as a temporary measure to prevent the failure of the entire system. It is often implemented during times of peak demand to avoid overloading the system.

An oil refinery is an industrial process plant where crude oil is processed and refined into more useful petroleum products, such as gasoline, diesel fuel, asphalt base, heating oil, kerosene and liquefied petroleum gas. Oil refineries are typically large sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units.

Load shedding can result in power outages, disrupting daily activities and operations. It can lead to economic losses for businesses, inconvenience for households, and potential safety hazards. Additionally, frequent load shedding can strain the power infrastructure and indicate issues with energy supply and demand management.

Most Pressurized Water Reactors (PWRs) built to date were around 1100 MWe (megawatts energy) output, but larger ones are now planned, up to 1600 MWe or more.

Nuclear power plants produce various amounts of energy relative primarily to the size of the reactor. For the generation of power, there is some minimum size that the plant will be to be able to be operated at a profit, or at least at some acceptable level of cost effectiveness. That minimum will vary, too, and from perhaps a few tens of megawatts upward.

Typical Pressurized Water Reactors (PWR) reactors built in the 1970's produce about 1100 MWe, whilst the latest designs range up to around 1500 MWe

No matter what the maximum power of a nuclear plant may be, the actual power being generated at any time depends entirely on the amount of fuel in the reactor, how it is modulated and by what material. Rods containing nuclear material are in a core that is regulated by rods of material that can absorb neutrons emitted by the radioactive material. By controlling the fission process you can control the energy released and used to generate steam power to run a turbine to produce electric power. Rates can be in the order of a few kilowatts to megawatts depending on the size of the reactor.

A cooling tower works by using the process of evaporation to remove heat from a system. Hot water from a heat exchanger is pumped to the top of the tower where it is distributed over the packing material. As the water flows down through the packing, some of it evaporates, which removes heat and cools the remaining water. The cooled water is then recirculated back to the heat exchanger to continue the cooling process.

Load shedding refers to the deliberate shutdown of electricity supply to certain areas by power providers to prevent a total blackout of the power system. This is done when the demand for electricity exceeds the available supply, helping to stabilize the grid and prevent system-wide failures.

Load shedding happens when there is not enough electricity available to meet the demand of all customers, and an electricity (public) utility will interrupt the energy supply to certain areas. It is a last resort to balance electricity supply and demand.

Load shedding can have numerous negative effects on society, including disruption to businesses, loss of productivity, damage to electrical appliances due to sudden power surges, and increased reliance on alternative power sources like generators. Additionally, it can lead to social unrest, health issues from lack of access to essential services, and overall decreased quality of life for affected individuals.
