Question

Two identical masses of 5 kg each fall on a wheel from a height of 10m will disturb the mass of 2 kg water the rise in the temperature of the water will be

Answer 1

Weight of mass = 5kg (Given)

Height = 10m (Given)

Mass of Water = 2kg(Given)

To calculate the formula used will be -

W = J Q

Therefore,

2m * g* h = J * m' * Cp * Delta T

= 2 *5*10*10 = 4.2 *(2* 1000* delta T)

= Delta T = 0.12°c

Thus, if the mass of water is disturbed, the rise in the temperature of water will be 0.12°c
