Suppose `300J` of work done on a system and `70cal`. Of heat heat is extracted from the system. What are the values of `dW , dQ and dU` with proper signs?

suppose 200 J of work is done on a system and 80.0 cal is extracted from the system as heat . In the sence of the first law of thermodynamics what are the values ( including algbraic signs ) of (a) W ,(b ) Q m and (c ) Delta E_(i n t) ?

A system absorbs 300 cal of heat. The work done by the system is 200 cal. Delta U for the above change is

A system absorbs 300 cal of heat. The work done by the system is 200 cal. Delta U for the above change is

A system is provided 50J of heat and work done on the system is 20J . What is the change in the internal enegry?

In a process, 701 J of heat is absorbed by a system and 394 J of work is done by the system. What is the change in internal energy for the process?
