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

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

One mole of a gaseous system absorbs 100 J of heat and does work equivalent to 50 . J . Calculate the change in the internal energy of the system.

During a process, a system absorbs 710 kJ of heat and does 250 J of work. Calculate the change in the internal energy of the system.

A system absorbs 400 J of heat and does work equivalent to 150 J on the surroundings. Calculate the change in the internal energy of the system.

A system absorbs 640 J heat and does work of 260 J, the change in internal energy of the system will be :

A system absorbs 115J heat from the surroundings and 290 J work is done on the system calculate the change in internal energy of the system.

A system is provided with 50 J of heat and the work done on the system is 10J .What is the change in internal energy of the system in joules ?
