What is isothermal process?

In which thermodynamic process the total internal energy of system remains constant?

An automobile engine develops \(62.84 kW\) while rotating at a speed of \(1200 rpm\). What torque does it deliver?

Write a note on free expansion in thermodynamic process.

What are mechanical equilibrium and thermal equilibrium?

What is a thermodynamic process? Give any two types of it.

The initial pressure and volume of a gas enclosed in a cylinder are \(2 \times 10^5 N / m ^2\) and \(6 \times 10^{-3} m ^3\) respectively. If work done in compressing the gas at constant pressure is \(150 J\), find the final volume of the gas.

A system releases \(125 kJ\) of heat while \(104 kJ\) of work is done on the system. Calculate the change in internal energy of the gas.

0.5 mole of gas at temperature \(450 K\) expands isothermally from an initial volume of \(3 L\) to final volume of \(9 L\).
(a) What is the work done by the gas? \(\left( R =8.319 J mol ^{-1} K ^{-1}\right)\)
(b) How much heat is supplied to the gas?

State zeroth law of thermodynamics. What are the limitations of first law of thermodynamics.

State first law of thermodynamics.
