1. Spy balloon is to be constructed of a material with a mass of 0.5kg. it will be filled with helium and must be able to carry and instrument payload of 50kg at an altitude of 1000m where the density of the air is 1.16 kg/m^3. what mass of helium will be required.

2. If the temperature of gas (measured in K) is doubled

a-the rms speed of the molecules doubles

b-the rms speed increases bh a factor of 2

c-the average kinetic energy quadruples

d-the average kinetic energy increases by a factor of 2

3. A 1-liter container of nitrogen gas (N2) at a temperature of 23c is intially at a pressure of 1.25 atm. because of a slow leak the pressure falls to 1.15 atm 1 hour later what is the leak rate in molecules/second?
