Viscosity decreases with increase in temperature is the reason for

Options

  1. AOnly (i) is correct
  2. BOnly (ii) correct
  3. CBoth are correct
  4. DBoth are incorrect

Correct answer

C. Both are correct

Step-by-step solution

The viscosity decreases with increase in temperature. Due to this reason, the hot water moves faster than cold water. Since in summer temperature is high, so more viscous oils are used in motorcars.
