Find the horse power of child if he can chew 10 grams ice in one minute.

Find the power of a person who can chew 30g of ice in one minute. Latent heat of ice =80cal//gm , J=4.2 joule // cal.

What power is gained by a man when he eats 100 g ice in one minute ? Latent heat of fusion of ice is 80 cal/gm.

Calculate the horse power of a man who can chew ice at the rate of 60g min.^(-1) . Given J = 4.2 J cal^(-1) and altent heat of ice = 80 cal g^(-1), 1hp = 746W .
