A gas initially at 27°C is heated upto 327°C,its average K.E will be:
Correct answer: A. Doubled
- A. Doubled
- B. Four times
- C. 300 times
- D. 327 times
Explanation
The average kinetic energy of a gas is directly proportional to its absolute temperature (in Kelvin). The initial temperature is 27°C = 300 K, and the final temperature is 327°C = 600 K. Since the absolute temperature is doubled, the average kinetic energy will also be doubled.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
