Ideal gas is contained in a thermally insulated and rigid container and it is heated through a resistance $100\Omega$ by passing a current of $1A$ for five minutes, then change in internal energy of the gas is

An ideal mono-atomic gas of given mass is heated at constant pressure. In this process, the fraction of supplied energy used for the increase of the internal energy of the gas is

Show that the internal energy of the air (treated as an ideal gas) contained in a room remains constant as the temperature changes between day and night. Assume that the atmospheric around remains constant and the air in the room maintains this pressure by communicating with the surrounding through the windows etc.

Which of the following statement(s) is/are true?
"Internal energy of an ideal gas ............"

The internal energy of a system remains constant when it undergoes

A gas is expanded from volume $V_0$ and $2V_0$ under three different processes. Process 1 is isobaric, process 2 is isothermal and process 3 is adiabatic . Let $△U_1,△U_2$ and $△U_3$ be the change in internal energy of the gas in these process. then : 

If energy (heat) Q is supplied to right part so that the piston moves to the left by $\frac{l}{4}$ then the change in internal energy of right part of cylinder is 

Explain heat, work and internal energy of a system.

One mole of an ideal diatomic gas undergoes a transition from A to B along a path AB as shown in the figure, The change in internal energy of the gas during the transition is:
