Q. Which statement is incorrect?

A) A curve plotted between $p$ and $V$ at constant temperature is called isotherm
B) A curve plotted between $p$ and $T$ at constant volume is called isochore
C) A curve plotted between $V$ and $T$ at constant pressure is called isobar
D) At absolute zero, the gas equation holds good
Explanation

(d)
At absolute zero temperature, KE of the gas is zero, volume of the gas is zero, heat constant is zero, pressure of a gas is zero, molecular motion cases thus no gas exists
