A gas sample enclosed in a rigid metal container at room temperature 20C has an absolute pressure p_1. The container is immersed in hot water until it warms to 40C. What is the new absolute pressure p_2?
Express your answer in terms of p_1.
I was told to use p_1/T_1=p_2/T_2
I got p_1/293=p_2/313, how can you get p_2 then?

Please help! 
Catie,
I really don't understand this
