A column of liquid is found to expand linearly on heating 5.25 cm for a 10.0°F rise in temperature. If the initial temperature of the liquid is 98.9°F, what will the final temperature be in °C if the liquid has expanded by 18.2 cm?

Calculate the amount of heat needed to boil 45.2g of acetic acid (HCH3CO2), beginning from a temperature of 57.1°C. Round your answer to 3 significant digits. Also, be sure your answer contains a unit symbol.

A 25.0 mL sample of Benzene at 19.9 degrees celcius was cooled to its melting point, 5.5 degrees celcius and then frozen. How much energy was given off as heat in this process?

13.0 g of cream at 22.4 °C are added to an insulated cup containing 150.0 g of coffee at 81.3 °C. Calculate the equilibrium temperature of the coffee. You may assume no heat is lost to the cup or surroundings, and that any physical properties of cream and coffee you need are the same as those of water. Be sure your answer has 3 significant digits. °C Xx10 X

If you combine 270.0 mL of water at 25.00 °C and 100.0 mL of water at 95.00 °C, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water. Trinal °C

A sample of copper was heated to 275.1 °C, then placed into 450 g of water at 21.0 °C. The temperature of the water rose to 29.7 °C. How many grams of copper were in the sample?

A metal sample weighing 128.00 grams and at a temperature of 98.2 degrees Celsius was placed in 45.50 grams of water in a calorimeter at 22.8 degrees Celsius. At equilibrium the temperature of the water and metal was 35.6 degrees Celsius.  What is the change in temperature of the metal (in degrees C)? (Report this as a positive value)

A 47.0-g sample of copper at 99.3 °C is dropped into a beaker containing 158 g of water at 18.2 °C. What is the final temperature when thermal equilibrium is reached? (The specific heat capacities of liquid water and copper are 4.184 J/g ⋅ K and 0.385 J/g ⋅ K, respectively.)

While heating two different samples of water at sea level, one boils at 102°C and one boils at 99.2°C. Calculate the percent error for each sample from the theoretical 100.0°C.

Calculate the heat change in kilocalories for freezing 265 g of water at 0 ∘C.
