1. The problem statement, all variables and given/known data An empty room in a house near the Atlantic coast has a volume of 45m3. What is the kinetic energy of all of the gas molecules in the room on a 30C summer day? 2. Relevant equations pv = nrt 3. The attempt at a solution I realize that this is an ideal gas law problem, but I have no idea where to start. How can I solve for anything if I'm only given volume and temperature?
