The first law of thermodynamics is a special case of

Find the change in internal energy of the system when a system absorbs $$2\  kcal$$ of heat and at the same time does $$500 J$$ of work

A refrigerator is

If heat is supplied to the system it 

For adiabatic processes (Letters have usual meanings)

Which one of the following is an isentropic process?

If $$\Delta Q$$ and $$\Delta W$$ represents the heat supplied to the system and the work done on the system respectively, then the first law of thermodynamics can be written as
