A system absorbs $600J$ of heat and work equivalent to $300J$ on its surroundings. The change in internal energy is:

A system absorbs 6 kJ of heat and does 1.5 kJ of work on its surroundings. The charge in internal energy is ………

A system absorbs 600 J of heat and does a work of 200 J on its surroundings. $\delta E$ of system is

Calculate the internal energy change for each of the following processes:
(i) A system absorbs 428 J of heat and does work equivalent to 286 J on its surroundings.
(ii) 62 J of work is done on the system and 128 J of heat is transferred to the surroundings.

A system absorbs 800 J of heat and system works equivalent to 900 J by expanding. The value of $\Delta U$ for the system is

A system is provided 50 J of heat and work can be done on the system is 10 J. The change in internal energy during the process is:

A system absorbs 100 cal of heat and does an external work of 150 J. if J=4.2 J/cal the change in internal energy is

A system absorbs $1000$ cal of heat and does $1675J$ work. If $J=4.18J/cal$, then find the change in internal energy of the system?

A system is provided 50J of heat and work done on the system is 10Joule What is the change in internal energy
