Why do some washing powders contain enzymes?
Enzymes in washing powders help break down stains and dirt by accelerating chemical reactions. This can make the washing process more effective at lower temperatures, reducing the need for hot water and harsh chemicals, and making the detergent more environmentally friendly.
What are the deviations of the ideal gas accounted for in the equations of state of real gass?
An ideal gas, by definition, follows the Ideal Gas Law, which states PV=nRT. Any behavior for which that equation does not hold is considered non-ideal. What then are the causes of non-ideal behavior? The Ideal Gas Law doesn't work for many gases (in other words, many gas are not actually ideal) because the Gas Law makes two assumptions, that in certain conditions break down. Assumption #1 is that there are no interactions between atoms/molecules in the gas phase. In this model, there are no attractive or repulsive forces between two neighboring atoms/molecules in the gas phase. This is not always correct, and especially at very low temperatures, gases tend to condense, and so attractive forces between them start to be significant. Attractive forces tend to make the measured pressure lower than it is predicted to be. Assumption #2 is that the volume of the container holding the gas is infinitely larger than the volume taken up by the gas molecules themselves. In other words, it assumes that molecules have zero volume, which is of course not true. This assumption breaks down significantly at very high pressures, where the volume taken up by the gas is significant compared to the volume of the container. To correct for this, the molecular volume taken up by the gas is subtracted from the volume of the empty container. Therefore, there are significant deviations from the Ideal Gas Law at high pressures or very low temperatures. The actual amount of deviation depends on the molecules individual properties. H2 gas or He gas are both very "ideal" gases under most conditions. However, H2O, with strong intermolecular attractive forces, or SO2 (a fairly large molecule also with strong intermolecular forces) do not obey the Ideal Gas Law under most conditions.
Does freezing's thermal energy increase or decrease?
When a substance freezes, its thermal energy decreases. This is because the molecules within the substance slow down and move closer together as they form a solid structure.
In a dc generator why does total flux per pole decrase if the load on the machine increases even thought the field current is constsn?
Due to armature reaction
What can we do to remove water pollution?
decrase the use of plastic etc...
Does the beta particle increase or decrase mass?
The beta particle decreases mass because it is an electron emitted from a nucleus during beta decay. The process of emitting a beta particle can result in the conversion of a neutron into a proton, leading to a decrease in the mass number of the nucleus.
How does the quality of water affect the rate of evaporation. Should it be considered for determining the rate of evaporation?
if quality of water reduce the evaporation will decrase
How can you decrase friction?
Depends what you want to increase/decrease friction on. If is like a weight on the floor.. Then to increase the friction all you have to do is increase the weight, To reduce it you either reduce the weight or get a smoother surface, or maybe a cloth in-between the floor and the weight.
Would weight increase or decrase on the surface of an earth sized planet with greater mass than earth?
If you're the same distance from the center of the planet but its mass is greater than earth's mass, then the mutual gravitational force between you and that planet is greater than on earth, and you'll "weigh" more than you do here.
How do you decrase friction?
You can decrease friction by using lubricants, reducing the weight or pressure on the surfaces in contact, using smoother surfaces, or introducing ball bearings or rollers to facilitate movement.
What is the definition of loadshading?
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.

What happen to the pressure as the temperature decrase?
If allowed to do work on the surroundings, the temperature will decrease as the pressure decreases. If expanded against a vacuum or adiabatically, most gases will get colder. At room temperature, all gases except hydrogen, helium, and neon cool upon expansion by the Joule-Thomson process; these three gases experience the same effect but only at lower temperatures; when starting at room those three gases will actually WARM when expanded across a valve.
How much does it cost to ship a car?
It depends on how big the car, where, and when you are shipping it. Coast to coast car shipping for a standard size sedan should range anywhere from $750 - $1,000. The rates should decrase during the slower winter months and increase during the busier season during the summer periods. Car shippers charge anywhere from $650 - $800 to transport sedans between New York to Florida. SUVs, vans and pickup trucks run about $900 - $1,000. The cars are put on a semi truck trailer. It can be either open or enclosed (for more protection). Enclosed is safer for your vehicle but cost more money. The trucks can come straight to your house and drop off where ever you like. == I'd have to disagree on cost just a little. While it does depend on the size of the vehicle you're shipping as well where it's coming from and going to, the prices have changed quite a bit. Most of the quotes I've received for mid-sized car from Italy to the Southeastern United States have quoted me close to $2,000.00. That's still not bad, but from Europe to the U.S. and vice versa, there is just no way the costs start around $750.00. If they do start that low, they must be cutting corners somewhere like not being fully covered. I'd rather not take that chance with my vehicle to pay a considerably cheaper price. I'd call and ask some companies directly. At least you can give them the details and they can give you an estimate based on your criteria.
