To determine the specific heat of an object, a student heats it to 100 ∘C∘C in boiling water. She then places the 55.4 gg object in a 179 gg aluminum calorimeter containing 129 gg of water. The aluminum and water are initially at a temperature of 19.9 ∘C∘C, and are thermally insulated from their surroundings. If the final temperature is 22.3 ∘C∘C, what is the specific heat of the objectand the type of material?

Suppose that on a dry, sunny day when the air temperature is near 37∘C, a certain swimming pool would increase in temperature by 1.75∘C in one hour if not for evaporation. What fraction of the water in the pool must evaporate during this time to carry away precisely enough energy to keep the temperature of the pool constant? The specific heat of water is 4186 J/(kg·∘C). At 37∘C, the latent heat of vaporization of water is 2430 kJ/kg. Assume that the water in the pool is close enough to 37 ∘C that this value for the latent heat can be used.

An insulated Thermos contains 100 cm3 of hot coffee at 82.0°C. You put in a 19.0 g ice cube at its melting point to cool the coffee. By how many degrees has your coffee cooled once the ice has melted and equilibrium is reached? Treat the coffee as though it were pure water and neglect energy exchanges with the environment. The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg. The density of water is 1.00 g/cm3.

An insulated beaker with negligible mass contains liquid water with a mass of 0.310 kg and a temperature of 82.6 ∘C. How much ice at a temperature of -16.1 ∘C must be dropped into the water so that the final temperature of the system will be 24.0 ∘C? Take the specific heat of liquid water to be 4190 J/kg⋅K , the specific heat of ice to be 2100 J/kg⋅K , and the heat of fusion for water to be 3.34×105 J/kg.   Thank you in advance I cannot understand physics to save the life of me.

A plastic cup of negligible mass contains 0.280 kgkg of an unknown liquid at a temperature of 36.0 ∘C∘C. A 0.0270 kgkg mass of ice at a temperature of 0.0∘C∘C is added to the liquid, and when thermal equilibrium is reached the temperature of the combined substances is 14.0 ∘C∘C. Assuming no heat is exchanged with the surroundings, what is the specific heat capacity of the unknown liquid? Express your answer in joules per kilogram-kelvin.

A closed box is filled with dry ice at a temperature of -88.3 oC, while the outside temperature is 18.8 oC. The box is cubical, measuring 0.309 m on a side, and the thickness of the walls is 3.80 × 10-2 m. In one day, 3.62 × 106 J of heat is conducted through the six walls. Find the thermal conductivity of the material from which the box is made.

A 26 grams silver ring (specific heat capacity: 234 J/Kg C)  is  heated to a temperature of 83.7 C and then placed in a calorimeter containing 0.05 Kg of water at 23.8 C. The calorimeter is not perfectly insulated, however, and 0.14 kJ of energy is transferred to the surroundings before a final temperature is reached. What is the final temperature?

An unknown material, m1 = 0.31 kg, at a temperature of T1 = 96 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.2 kg of water at T2 = 22 degrees C. Water has a specific heat of cw = 4186 J/(kg⋅K). After the system comes to equilibrium the final temperature is T = 32.8 degrees C. What is the specific heat of the unknown material in J/(kg⋅K)?

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).
