How will you find the change in internal energy of a system when it melts ?

Define internal energy of a system.

The change in the internal energy of a substance

1 g of water at 100^(@)C is converted into steam at the same temperature. If the volume of steam is 1671 cc find the change in internal energy of the system. Latent heat of steam =2256 J g ^(-1).

A system absorbs 1500 joule of energy as heat and produces 500 joule of work .the change in internal energy of the system will be :

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?

Enthalpy change equal internal energy change when

What is the change in internal energy of a system undergoing a cyclic process, at the end of a cycle ?

What is the change in the internal energy of a system over one complete cycle of a cyclic process?

Statement I: When an ideal gas is taken from a given thermodynamics state A to another given thermodynamic state B by any polytropic process, the change in the internal energy of the system will be the same in all processes. Statement II: Internal energy of the ideal gas depends only upon its absolute temperature.

Refer to figure. Let DeltaU_(1) and DeltaU_(2) be the changes in internal energy of the system in the processes A and B. then
