Embibe Experts Solutions for Chapter: Thermodynamics, Exercise 1: Exercise

"Two systems in thermal equilibrium with a third system separately are in thermal equilibrium with each other." This statement refers to which law of thermodynamics?

Pressure $P$, volume $V$ and temperature $T$ of a certain material are related by $P=\frac{\alpha T^2}{V},$ where $\alpha$ is constant. Work done by the material when temperature changes from $T_0$ to $2T_0$ and pressure remains constant is

For a gas $\frac{R}{C_v}=0.4,$ where $R$ is the universal gas constant and ${ }^{}{C}_v^{}$ is the molar specific heat at constant volume. The gas is made up of molecules which are

Find the percentage decrease in the volume if the pressure of an ideal gas is increased by $60 \%$ at constant temperature.
 

$P-T$ graph for same amount of an ideal gas is allowed to expand as shown in the figure below. Then which of the following is right?

You are riding on your bicycle with inflated tyres. Your friend asks for a lift and sits on the carrier behind you

Which type of molecular motion does not contribute towards internal energy:-

An ideal gas is reversibly around the cycle $a-b-c-d-a$ as shown on the $T$ (temperature) $-S$ (entropy) diagram

The most appropriate representation of the above cycle on a $U$ (internal energy) $-V$ (volume) diagram is-
