What happens to the internal energy of a system when work is done on it?
If the internal energy of the system increases the temperature will increase.
When a system does work and no heat is added to the system its temperature?
remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.
It isn't possible to transfer heat from an object at a lower temperature to another object at a higher temperature unless?
It isn't possible to transfer heat from an object at a lower temperature to another object at higher temperature unless work is done to the system. An example of this is a refrigerator.
when work is done on a system by an external force, the system?
When work is done by an external force, the system will have more energy in it than it did before.
What happens to the internal energy of a system when work is done on it?
If the internal energy of the system increases the temperature will increase.
What happens to a substance when the pressure goes up?
The substance will be compressed (increase in density) and if the compression is adiabatic, the temperature will go up since there is work being done on the system.
When mechanical work is done on a system there is an increase in what?
both temperature and internal energy

remains constant From Rafaelrz. When a simple closed system does work and no heat is added, the temperature of the system will drop. This is because the work is done at the expense of his internal energy, which is thermal energy.
Expansion happens because?
there is too much pressure in a system. example, a system which has done work and releases heat will expand itself
Describe what happens to air temperature when work is done on the air to compress it?
Yes. As the molecules become closer, the collisions increase, increasing temperature.
Is the work-done in isothermal system is zero why?
If a reaction is carried out in constant temperature and constant volume no work is done and heat exchanged with surroundings is equal to the internal energy.

What research has been done on narcolepsy?
a neuropeptide system in the hypothalamus, the part of the brain that regulates body temperature and appetite. The newly discovered system, which has been called the hypocretinergic system, regulates sleep
when work is done on a system by an external force, the system?
When work is done by an external force, the system will have more energy in it than it did before.
How does frost get on the ground?
what happens is it rains and the temperature might be low so it might be cold and when it's done raining the rain freezes and turns in to snow
