A mass m_u = 100 g of liquid water sits in an insulated cup at temperature T_w = 10 degree C. Ice at temperature T_i = -10 degree C is added, and the mixture comes to thermal equilibrium when exactly half of the ice has melted. Find the mass of ice added, m_i. Solve this for the general case of any substance where the solid form of the substance is added to the liquid form. Follow the steps below: Specify...

a new liquid substance has been discovered the freezes at 50
degrees celsius. a scientist poured the liquid (which was at 50
degrees celsius) into a 0.68 kg cup which caused some, but not all,
of the liquid to freeze (only 0.22 kg of the liquid froze). as a
result, the cup gained 67000 J of heat until thermal equilibrium
was reached. determine the latent heat of the substance & the
initial temperature of the cup.

A piece of solid cadmium weighing 37.6 g at a temperature of 311 °C is placed in 376 g of liquid cadmium at a temperature of 370 °C. After a while, the solid melts and a completely liquid sample remains. Calculate the temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings. The enthalpy of fusion of solid cadmium is ΔHfus = 6.11 kJ/mol at its melting point of 321 °C, and the molar heat capacities for...
