Explanation Given Info : Mass of the block is 1.50 kg, mass of the water is 0.200 kg, and the distance the block fall is 3.00 m. Formula to the change in potential energy of the blocks is, P E = 2 m B g h PE is the change in potential energy of the block, m b is the mass of the block, g is the acceleration due to gravity, h is the distance the block fell, The 2 in the above equation is due to two masses. Formula to calculate the increase in internal energy of the system is, Q = m W c Δ T Q is the increase in internal energy of the system, m W is the mass of the water, c is the specific heat of the water, Δ T is increase in the temperature, The change in internal energy of the block is added to the internal energy of the system. Formula to calculate the change in internal energy of the system is, Q = P E Use m W c Δ T for Q and 2 m B g h for PE in the above equation and rearrange it in terms of Δ T . m W c Δ T = 2 m B g h Δ T = 2 m B g h m W c Substitute 1
