Question
Four systems are at the following temperatures in degree Celsius. the speed of particles of which of the systems is the lowest?
- 35
- 87
- 12
- 76
Hint:
Kinetic energy or speed of the particles varies according to temperature
The correct answer is: 12
As the body having lowest temperature will have least heat energy, the particles motion won't be that random so kinetic energy of the particles would be less.
