A 0.050-m tank holds hydrogen (H2) at a pressure of 4 106 Pa at a temperature of 300 K. How many molecules (that's molecules, not moles) are contained in the tank? 7.* Gas in a propellant tank on board a spacecraft registers a pressure of 8,000 Pa when it is at 20 C. When the spacecraft turns so that the tank is in direct sunlight, its temperature rises to 40 C. What is the new pressure in the tank? [Hint: If you got 16,000 Pa you had better think about the question again.] A 0.050-m tank holds hydrogen (H2) at a pressure of 4 106 Pa at a temperature of 300 K.
