Unformatted text preview: uses a nitrogen cold gas thruster to provide small bursts of thrust. The pressure and temperature in the tank at the beginning of the thrusters lifetime (launch) is 30 atmospheres and 300 K, respectively. After 1 year of operation in the cold space environment the pressure and temperature within the tank are 15 atmospheres and 150 K. During this time, the density of the nitrogen has (increased by a factor of 10 / decreased by a factor of 10 / increased by a factor of 2 / decreased by a factor of 2 / remained the same). This question is based on the ideal gas law: p= RT. Writing the ideal gas law for both cases it can be seen that the density will remain constant....
