A gas cloud is in pressure equilibrium with its surroundings,which have a temperature of 10⁴ K.If the gas cloud is 100 times denser than the surrounding medium,what is its temperature?

Question

Quizplus · Accepted Answer

In pressure equilibrium, the pressure inside the gas cloud equals the pressure of the surroundings. Pressure is proportional to the product of density and temperature. If the gas cloud is 100 times denser, its temperature must be 100 times lower to maintain the same pressure, so the temperature is 100 K.
