In the upper atmosphere the kinetic temperature of air is of the order of 1000 K, even then one feels severe cold there.

At upper atmosphere, an astronaut feels

At what temperature(K) the kinetic energy of a gas molecule is one-half of its value at 30^(@)C ?

A certain gas is at a temperature of 350 K . If the temperature is raised to 700 K , the average translational kinetic energy of the gas will increase by

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 290K and the substance cools from 370K to 330K in 10min, when will the temperature be 295K?

A bulb contains air at atmospheric pressure at 40^(@)C . The maximum pressure bulb can with stand is 2 atmosphere. Calculate the temperature of air when the bulb is on the point of bursting.

In a Carnot engine the temperature of source is 1000 K and the efficiency of engine is 70%. What is the temperature of the sink ?
