The critical temperature and reduced temperature of a gas are 150 K and 3 respectively. What is the temperature of the gas ?

The rate at which a substance cools in moving air is proportional to the difference between the temperatures of the substance and that of the air. If the temperature of the air is 290 K and the substance cools from 370 K to 330 K in 10 min, when will the temperature be 295 K?
