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.
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.
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.
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.
Work done on the system is?
work done on the system: when a surrounding does work on the system the total energy increases so work done is positive..........
When mechanical work is done on a system there is an increase in what?
both temperature and internal energy

A heat engine takes in 100J of energy from the high temperature reservoir and expels 80J into the low temperature reservoir so how much work was done by the engine?
a lot.
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.
Have you done your work What is the passive voice of this sentence?
Has your work been done by you?
What is work done if there is nodisplacement is 0?
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
What is the max temperature at which soft soldering is done is?
The maxinum temperature in which soft soldering is done is 800 F
How does the temperature vary across the gas turbine is there a formula for getting the work done in the turbine?
Read up on thermodynamics and then read the link concerning the Brayton Cycle. The temperature peaks just before it reaches the exhaust.
