A mass of 1.8kg of water at 17.9*C is poured from a height of 1.6m into a vessel containing 8.8kg of water at 17.9*C.

(a) How much does the internal energy of the 10.6 kg of water increase?

(b) Is it likely that the water temperature will increase? (Yes/No? )

(c) The increase in internal energy ____________(increases/decreases) the average kinetic energy of the water molecules, thus the temperature is slightly______________ (increased/decreased).

1. A flask holds 9.73 kg of a monatomic ideal gas (mass number 86.4). If the gas changes temperature isochorically (constant volume) from temperature 802o C to 376o C, find the change in the internal energy of the gas, in kJ. A positive answer means the internal energy increased; a negative answer means the internal energy decreased.   2. A flask holds 2.25 kg of a diatomic ideal gas (mass number of the gas 92.1).

An unknown substance has a mass of 0.125 kg and an initial temperature of 79.8°C. The substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water initially at 21.0°C. The mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32.0°C. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance.
