Embibe Experts Solutions for Chapter: States of Matter: Gases and Liquids, Exercise 1: Exercise 1

One mole of ${\mathrm{N}}_2( \mathrm{g})$ is taken in $1$ litre empty container fitted with a movable piston at $300\mathrm{K}.$ If it is heated to $1200\mathrm{K}$ at constant pressure then match the change (List$-\mathrm{II}$) in parameters (List $- \mathrm{I}$) of gas as compared to initial state $\&$ select the correct code.

If the distribution of molecular speeds of a gas is as per the figure shown below, then the ratio of the most probable, the average, and the root mean square speeds, respectively, is:

Two containers are connected by a tube of negligible volume, container$\left(\mathrm{I}\right)$ has ${\mathrm{N}}_2\left(\mathrm{g}\right)$ gas at pressure $4$ atm and temperature $\mathrm{T}\left(\mathrm{K}\right)$ and container$\left(\mathrm{II}\right)$ has $1$ litre ${\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$ at temperature $\left(\mathrm{T}\right)$ initially. Find correct option(s) after stopcock is removed. (aq. Tension $=190$ torr)
