When the same amount of heat is applied to both, which will heat up to a higher temperature—a given mass of water or that same total mass of water and steel together? Why?

A 45.90 g sample of pure copper is heated in a test tube to 99.40°C. The copper sample is then transferred to a calorimeter containing 61.04 g of deionized water. The water temperature in the calorimeter rises from 24.51°C to 29.10°C. The specific heat capacity of copper metal and water are J and 4.184 J respectively. g• °C 0.387 g• °C Assuming that heat was transferred from the copper to the water and the calorimeter, determine th heat capacity of the calorimeter. Heat capacity of calorimeter =

18. An unknown volume of water at 18.2°C is added to 24.4 mL of water at 35.0°C. If the final temperature is 23.5°C, what was the unknown volume? (Assume no heat is lost to the surroundings; d of water = 1.00 g/mL)

Enthalpy is the a. Heat of combustion at constant pressure b. Heat of formation at constant pressure c. Change in energy of a system at constant pressure d. Energy of a system at constant pressure
