What mass of steam at 100°C must be mixed with 185 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 60°C?

A styrofoam cooler (k = 0.030 W/(m-°C) has outside dimensions of 0.170 m x 0.250 m x 0.260 m, and an average thickness of 2.0 cm. How long will it take for 1.10 kg of ice at -5.0°C to melt (to water at 0°C) in the cooler if the outside temperature is 34.0°C? Assume that ice temperature increases linearly from -5.0°C to 0°C. Neglect any temperature change of the air in the cooler. Data: Specific heat of ice is 2050 J/(kg-K). Laten heat of fusion of water is 3.34×105 J/kg.

What mass of water at 28.0°C must be allowed to come to thermal equilibrium with a 1.75-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 66.0°C? Assume any water turned to steam subsequently recondenses

Suppose 6.6 kg of chloroform at 24.4°C is poured into 6.6 kg of propylene glycol at 37°C. Calculate the final equilibrium temperature, neglecting any energy processes associated with mixing, given Cprop = 2500 J/(kg-K) and Cchloroform = 1050 J/(kg-K). T = °C

What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.95-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 60.0°C? Assume any water turned to steam subsequently recondenses. kg

Ice has formed on a shallow pond, and a steady state has been reached, with the air above the ice at -7.6°C and the bottom of the pond at 3.7°C. If the total depth of ice + water is 2.3 m, how thick is the ice? (Assume that the thermal conductivities of ice and water are 0.40 and 0.12 cal/m-Cº-s, respectively.) Number Units

Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 11.5-L capacity when at 11.0°C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0°C operating temperature, given the fluid's volume coefficient of expansion is 400 ✕ 10^−6/°C and that of copper is 51 ✕ 10^−6/°C. Note that most car radiators have operating temperatures of greater than 95.0°C.

What mass of water at 20.0°C must be allowed to come to thermal equilibrium with a 1.90-kg cube of aluminum initially at 150°C to lower the temperature of the aluminum to 70.0°C? Assume any water turned to steam subsequently recondenses. kg
