What is the volume occupied by 7.0 g of hydrogen under a pressure of 2.6 atm and a temperature of 300 K?

answer is .0332 m^3. how?


A steel cylinder of radius 7.0 cm and length 4.0 cm is placed in end-to-end thermal contact with a copper cylinder of the same dimensions. If the free ends of the two cylinders are maintained at constant temperatures of 85C (steel) and 20C (copper), how much heat will flow through the cylinders in 19 min?

answer is 1.17*10^6. how?

THANKS A TON. test on these tomorrow and ive been trying to do em for like an hour :\
