Heat is not being exchanged in a body. If its internal energy is increased, then

Heat is supplied to a system, but its internal energy does not increase Obtain an expression for the work done in the above process.

Heat is supplied to a system, but its internal energy does not increase Which process is the involved in this case?

The temperature of a gas is increasing, hence its internal energy also increases. Just be observing initial and final states, can we determine whether the internal energy increment was due to work or by heat transfer.

A piece of lead is hammered. Does its internal energy increase? Does the heat enter the lead from outside?

When an ideal diatomic gas is heated at constant pressure, its internal energy increased by 50cal then the work done by the gas is

A piece of leads is hammered. Does its internal energy increase? Does the heat enter the lead from outside ?

A piece of leads is hammered. Does its internal energy increase? Does the heat enter the lead from outside ?

An ideal gas is compressed isothermally . Does its internal energy increase ?
