the specific heat capacity of milk is 3930 J/(kg*K). Find the final temperature if 312 g of milk at 21.8 celcius is mixed with 189 g of milk at 95.2 celcius.

Arelyz and Hyeonggyun drop a 378.0-g piece of metal at 100.0°C into 447.0 g of water at 20.0°C. The final temperature of the system is measured to be 50.0°C. What is the specific heat of the metal in J/kgK, assuming no heat is exchanged with the surroundings or the cup containing the water? The specific heat of water is 4190 J/(kg K).

A Styrofoam box has a surface of 0.78 m² and a wall thickness of 22.5 cm. The temper- ature of the inner surface is 1.8°C, and of the outside 12°C. If it takes 17.3 hours for 86 kg of ice to melt in the container, find the thermal conductivity of the Styrofoam. The latent heat of fusion of water is 3.34 x 105 J/kg. Answer in units of W/m/°C.

A copper block with a mass of 400 grams is cooled to 77 K by being immersed in liquid nitrogen. The block is then placed in a Styrofoam cup containing some water that is initially at +50.0°C. Assume no heat is transferred to the cup or the surroundings. The specific heat of liquid water is 4186 J/(kg °C), of solid water is 2060 J/(kg °C), and of copper is 385 J/(kg °C). The latent heat of fusion of water is 3.35 x 105 J/kg. What is the mass of water in the cup, if the final temperature is -25.0°C?

What mass of water could be warmed from 21.9°C to 52.1°C by the pellet dropped inside it? Heat capacity of the pellet is 53 J/°C. The pellet is initially at 113°C.

Ice at 0 °C is placed in a Styrofoam cup containing 0.62 kg of lemonade at 32 °C. The specific heat capacity of lemonade is virtually the same as that of water; that is, c = 4180 J/(kg C°). After the ice and lemonade reach an equilibrium temperature, some ice still remains. The latent heat of fusion for water is Lf = 3.35 x 105 J/ kg. Assume that the mass of the cup is so small that it absorbs a negligible amount of heat, and ignore any heat lost to the surroundings. Determine the mass of ice that has melted, in grams.

A bar of pure gold is heated to 105.0 °C. The specific heat capacity of gold is 1.29x10² J/1kg~°C). The gold is placed into 600.0 mL of ethyl alcohol initially at a temperature of 35.0 °C. The final temperature of the mixture is 37.0 °C. What is the mass of the gold?

A chunk of metal with a mass of 85.0 grams and a specific heat of 759 joules per kilogram·kelvin is heated to 78.9 degrees Celsius and placed in 122 milliliters of water (c = 4186 J/kg·K) at 18.6 degrees Celsius. What is the final temperature of the metal and water? Hint: The heat lost by the metal is gained by the water, so the sum of the heats is zero.

A rectangular block of aluminum has the following dimensions: 1m x 1m x m. The density of aluminum is 2700kg/m^3. The specific heat of aluminum is 0.9 J/g K. How much does the block of aluminum weigh in Newtons?
