Question

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

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

hintHint:

More the temperature of water, more will be the speed of the particles

The correct answer is: Smaller than


    More the temperature of water, more will be the speed of the particles, so in first case as the temperature was lesser as compared to in second case, the speed will be less in first case
