Question

Case 1: Water is heated to a temperature of 40 degree Celsius.
Case 2: It is heated further to 70 degrees Celsius.
The KE of the molecules in case 1 is __ the KE of the molecules in case 2.

  1. Equal to
  2. Greater than
  3. Smaller than
  4. Any of the above

Hint:

Temperature increases the KE of the system

The correct answer is: Smaller than


    More temperature means more KE, therefore as the temperature is more in case 2, the KE is more there
