A liquid cools down from

{70^0}C

{60^0}C

in 5 minutes . The time taken to cool it from

{60^0}C

{50^0}C

will be

View answer and explanation

Correct option: C

Greater than 5 minutes

Option C (Greater than 5 minutes) is correct because as the temperature difference between the liquid and surroundings decreases, the rate of cooling slows down according to Newton's Law of Cooling.

Four identical calorimeters painted in different colours, are heated to same temperature and then allowed to cool in vacuum. Which will cool fastest? An ice cube of dimensions

60 \mathrm{~cm} \times 50 \mathrm{~cm} \times 20 \mathrm{~cm}

is placed in an insulation box of wall thickness

1 \mathrm{~cm}

. The box keeping the ice cube at

0^{\circ} \mathrm{C}

of temperature is brought to a room of temperature

40^{\circ} \mathrm{C}

. The rate of melting of ice is approximately.

(Latent heat of fusion of ice is

3.4 \times 10^5 \mathrm{~J} \mathrm{~kg}^{-1}

and thermal conducting of insulation wall is
