A 100kg of commercial tungsten (C=138J/kg-K) at a temperature of 180oC and 45kg of diamond (C=520J/kg-K) at a temperature of 135oC is placed inside an insulated container containing ice at freezing temperature. If heat is restricted to escape, determine the mass of the ice if the temperature of the mixture when equilibrium is attained is about 73.53oC.

8. A 1.90-kg piece of aluminum that has a temperature of -159 °C is added to 1.80 kg of water that has a temperature of 3.5 °C. At equilibrium the temperature is 0.0°C. Assuming that the heat exchanged with the container and the surroundings is negligible, determine the mass of water that has been frozen into ice. grams

A 0.1 kg block of pure copper at a temperature of 250°C is dropped into a 4°C water bath. The bath contains 0.03 m^3 of water and is well insulated. Find the final temperature after the block and the water reach thermal equilibrium. (It is reasonable to assume the following: the specific heat of water is equal to the value at 4°C; the specific heat of the material in the block can be taken to be a constant value evaluated at a temperature mid-way between the initial temperatures of the block and the water.)

A real gas exists at 130 C and 1.2 MPa. It is known that the critical temperature and critical pressure of the gas is 374.2 k and 4.059 MPa. It is also know that the ideal gas constant (R) of the gas is 0.12 kPa-m/ S/kg-K. In the question that follows, select the answer that is closest to the true value. Use the compressibility factor (Z) to determine the specific volume in units of m/kg. ,3, Tuesday Dece mber 7 2021 5:52:58 DM CST
