NOTE: Answer in grams. Given: The specific heatofwater is 4186 J/kg ·? C.

A jar of tea is placed in sunlight until it reaches anequilibriumtemperature of 33.7?C. In an attempt to coolthe liquid,which has a mass of 194 g , 91.9 g of ice at0.0?C isadded. Assume the specific heat capacity of thetea to be that ofpure liquid water. At the time at which thetemperature of the teais 29?C, find the mass of theremaining ice in the jar.Answer in units of g.

What mass (in grams) of steam at 100°C must be mixed with 298 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 15.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg, and the latent heat of vaporization is 2256 kJ/kg.

1. Suppose0.0290 kg of steam (at 100.00°C) is added to 0.290 kg of water(initially at 19.1°C.). The water is inside a copper cup of mass27.3 g. The cup is inside a perfectly insulated calorimetrycontainer that prevents heat flow with the outside environment.Find the final temperature (in °C) of the water after equilibriumis reached.

2. A coppersheet of thickness 2.25 mm is bonded to a steel sheet of thickness1.29 mm. The outside surface of the copper sheet is held at atemperature of 100.0°C and the steel sheet at 26.1°C.

3. Fora class demonstration, your physics instructor pours 1.18 kg ofsteam at 100.0°C over 4.81 kg of ice at 0.0°C and allows the systemto reach equilibrium. He is then going to measure the temperatureof the system. While the system reaches equilibrium, you are giventhe latent heats of ice and steam and the specific heat of water:Lice = 3.33·105 J/kg,Lsteam =2.26·106 J/kg, cwater =4186 J/(kg °C). You are asked to calculate the final equilibriumtemperature (in °C) of the system. What value do youfind?
