When 200 g of Aluminum at 100°C is dropped into an aluminum calorimeter of mass 120g and containing 150 g of kerosene at 15°C, the mixture reaches a temperature of 50° C. What is the specific heat of kerosene?

When 200g of aluminum at 100° c is dropped into aluminum calorimeter of mass 120 g and containing 150g kerosene at 15° C, the mixture reaches at temperature of 50° C. What is the specific heat of kerosene? (sp. Ht. of Al = 0.214 cal/g-°C)

A 215-g sample of a substance is heated to 330°C and then plunged into a 105-g aluminum calorimeter cup containing 165 g of water and a 17-g glass thermometer at 12.5°C. The final temperature is 35.0°C. What is the specific heat of the substance? (Assume no water boils away.)

To determine the specific heat of an object, a student heats it to 100C in boiling water. She then places the 38.0g object in a 155g aluminum calorimeter containung 103g of water. The aluminum and water are initally at a temperature of 20.0C, and are thermally insulated from their surroundings. If the final temperature is 22.0C, what is the specific heat of the object?
