## Homework Statement

The question I am stuck on is "0.253 m of gas is compressed isothermally from a pressure of 1 bar until its volume is 0.0313 m. Calculate the heat energy transfer. "

## Homework Equations

I understand that work done = Heat transfer because it is isothermal but the equation I have to work with is:

Q=nRT ln V^2/V^1

I don't want the answer to this because I would like to understand, I just don't know what nRT is and how on Earth do I find T if it is not given in the answer.

## The Attempt at a Solution

I have not attempted to answer yet
