`w` is positive when the work is done on the system. (T/F)

if work is done by the system then W is

When the work is done by the system, w is taken as ......

Calculate the changes in internal energy of a system if, 300 J of heat energy is added to the system and a work of 160 J is done on the system.

We consider a thermodynamic system. If DeltaU represents the increase in its internal energy and W the work done by the system, which of the following statements is true?

What is the value of DeltaE when the work done by the system is equal to the heat absorbed by the system?

What happens to the internal energy of a system if work is done on the system.

When a system is taken from A to C through path ABC, 10 J of heat flows to the system and 4 J of work is done by the system. How much heat flows into the system in path ADC, if the work done by the system is 3 J ?

When a system is taken from state 'a' to state 'b' along the path 'acb', it is found that a quantity of heat Q = 200 J is absorbed by the system and a work W = 80 J is done by it. Along the path 'adb', Q = 144 J In the above question, if the work done on the system along the curved path 'ba' is 52J, heat absorbed is

When the state of a system changes from A to B adiabatically the work done on the system is 322 joule. If the state of the same system is changed from A to B by another process, and heat required is 50 calories of heat is required then find work done on the system in this process? (J = 4.2 J//cal)
