Two containers, X and Y, both contain nitrogen gas at a temperature of 30° C and a pressure of 1 atm. The initial volume of each of the containers is V30 = 0.5 liters. The only difference between the two containers is that while container X has a piston that is sealed and cannot move, the gas in container Y is allowed to expand against the surrounding atmosphere. QX is the amount of heat required to raise the temperature of the gas in container X by 10° C, and QY is the amount of heat required to raise the temperature of the gas in container Y by 10° C. What is the difference between QX and QY? Use 0°C = 273.15 K

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
