Energy

Max Planck considered quantized the energy of vibrating atoms, leading to the development of quantum theory. He proposed that energy is emitted or absorbed in discrete units or "quanta," rather than in a continuous manner.

Everyone wants to be in a state of maximum stability and so is the case of elements.

The elements in their free state are unstable and don't have stable electronic configuration.

By gaining, loosing or sharing electrons they achieve noble gas configuration

which is stable and thus the element gets its stability.

Collisions of electrons with other particles in a circuit can result in energy loss in the form of heat. This occurs due to resistance in the circuit, which causes a portion of the electrical energy to be converted into thermal energy. The charge of the electrons remains constant during these collisions.

You can prove it by using an energy monitor that measures the actual energy consumption of the light bulb. The wattage directly correlates to the amount of energy used by the bulb, regardless of its physical size. A higher wattage bulb will consume more energy than a lower wattage bulb, even if they are of the same physical size.

The problem with wind energy is that it does not produce much electricity. Wind does not flow at all places. So having wind energy as a major source of electricity is not a option.

The unit used to describe the amount of electrical energy provided by an energy source is the kilowatt-hour (kWh). It represents the amount of energy consumed or produced by using 1 kilowatt of power for 1 hour.

The SI unit of binding energy is the joule (J), which is a derived unit representing the energy required to separate a nucleus into its individual protons and neutrons. This energy reflects the strength of the nuclear force that binds particles together within the atomic nucleus.

Light energy is converted into electrical energy in the retina of the eye. The retina contains specialized cells called photoreceptors (rods and cones) that detect light and convert it into electrical signals that can be transmitted to the brain via the optic nerve.

Volts are used to measure the electrical potential difference or voltage in a circuit. To use volts, you would typically measure the voltage across a component in a circuit using a multimeter or voltmeter. This helps in determining if the component is receiving the correct amount of voltage for proper operation.

Yes, apart from small additions when meteorites fall to earth from space

The latent heat of vaporization of water is approximately 2260 kJ/kg at standard atmospheric pressure and temperature. This is the amount of energy required to change 1 kg of liquid water at its boiling point into steam at the same temperature.

When the child is up in the air on either side of the climax of the swing, it builds potential energy to drop or swing back down towards the other side. When the child falls, gravity and the potential energy work together to make the child fall, and in turn, the kinetic energy not used for the fall goes into pushing the child back up on the other side. Say that there was no gravity involved in this situation. The child would only make it to the bottom of the swing, closest to the ground, because the amount of energy you store up in going higher cannot be amounted to greater as you swing down.

The yoyo is a good example of how potential and kinetic energy can oscillate. When fully up and stationary it has zero kinetic and only potential, when it is fully down and rotating at max speed this energy has been converted to kinetic, then it climbs up again, and so on. The player has to keep providing a small input of energy to overcome friction losses.

Actually, your wrong. Sure, the lighting ithat is set for proper illumination is 60watts, but if anyone is used to using a dimmer, you can dial down the power consumption for a typical incandescent bulb and it will still light. And as expected, the light level will decrease as you lower the dimmer setting as well.

The First Law of Thermodynamics states that the internal energy of a system is a function of temperature. It describes the relationship between heat transfer, work done, and changes in internal energy. It is a fundamental principle in the field of thermodynamics.

Energy is transferred between the oceans and the atmosphere through processes like evaporation and condensation. The sun heats the ocean surface, causing water to evaporate and release latent heat into the atmosphere. This latent heat is later released when water vapor condenses to form clouds, leading to the transfer of energy between the two systems.

1. the filament of electric bulb is made up of tungsten as it has melting point of 3380 degree & it cannot be oxidised

2. electric fuse As a safely device which works on heating effect of electric current. the fuse wire is made up of copper, lead & tin. if a current larger than the specified value close to the circuit, the temperature of fuse wire increase. this melts the fuse wire & breaks the circuit.

Yes, a machine can convert mechanical energy into hydraulic energy (i.e., pump water up), and a machine can convert the hydraulic energy into mechanical energy. Some energy will be wasted in both cases, meaning that if you try to do this "back and forth" several times, the total energy available will decrease.

The thermal energy of particles can be calculated using the formula: E = (3/2)kT, where k is the Boltzmann constant (1.38 x 10^-23 J/K) and T is the temperature in Kelvin (room temperature is approximately 298 K). Substituting these values, the thermal energy of a hydrogen atom at room temperature would be around 6.21 x 10^-21 J.

The thermosphere and exosphere layers of the atmosphere have little thermal energy because they are very thin and have low air density. These layers are composed of very few gas molecules, which results in very high temperatures but low thermal energy due to the lack of molecules to transfer heat.

Metals conduct thermal energy through the movement of free electrons. When heat is applied, the free electrons gain kinetic energy and move through the metal, colliding with lattice vibrations and transferring their energy. This process allows thermal energy to be rapidly transferred through the metal.

The sun primarily produces electromagnetic radiation, such as visible light and heat, which provide us with energy. This energy is essential for sustaining life on Earth through processes like photosynthesis, which converts sunlight into chemical energy for plants.

There are four terrestrial planets: Mercury, Venus, Earth, and Mars. Of these, only the Earth really qualifies as "constantly reshaped by plate tectonics."

potential energy is found in things like a compressed spring, or a weight that has been raised to drive a clock. In it's static position, before the energy is released, it is being "stored". It usually changes into "kinetic" energy, causing something to move, or giving it momentum. Some of that energy will also be consumed by friction in the mechanism creating thermal energy.

The regulator has an inlet and outlet. There is a valve at the inlet typically called a seat valve or similar. This seat is linked to a diaphragm. This diaphragm separates the upper and lower halves of the regulator body and also serves as the gasket for the two halves. On top of the diaphragm is a spring, below is the inlet seat.

When no appliances are in use the lower section fills with gas, pushes the diaphragm up which seats the inlet valve and stops gas flow into the regulator. When an appliance is turned on, the gas flows out of the regulator and down the pipe to the appliance. When this happens the diaphragm lowers, opens the seat valve and gas once again flows.

The seat valve has an orifice to reduce the speed at which the upstream gas enters the regulator, and the diaphragm spring determines how much pressure it takes to close the seat.
