Q1: Joule-Thomson co-efficient is the ratio of

A pressure change to temperature change occuring during adiabatic compression of a gas.

B pressure change to temperature change occuring during adiabatic throttling of a gas.

C temperature change to pressure change occuring during adiabatic compression of a gas.

D temperature change to pressure change occuring during adiabatic throttling of a gas.

ANS:D - temperature change to pressure change occuring during adiabatic throttling of a gas.

The Joule-Thomson coefficient (also known as the Joule-Kelvin coefficient) is defined as the temperature change with respect to pressure change occurring during adiabatic throttling of a gas. So, the correct option is: "temperature change to pressure change occurring during adiabatic throttling of a gas."
