A vessel contains water. Paddles that are propelled by falling masses turn in the water, causing the water's internal energy to increase.
A vessel contains water. Paddles that arepropelled by falling masses turn in the water,causing the water’s internal energy toincrease. The temperature of the water is thenmeasured, giving an indication of the water’sinternal energy increase.If a total mass of 12.4 kg falls 5.76 m andall of the mechanical energy is converted tointernal energy, by how much will the internalenergy of the water increase? The accelerationof gravity is 9.81 m/s2 . (Assume noenergy is transferred as heat out of the vesselto the surroundings or from the surroundingsto the vessel’s interior.)
