An experiment is conducted where 1.00g of water has an initial temperature of 25°C. A metal has a mass of 5.00g and has an initial temperature of 100°C. Assume the heat capacity of the metal is Cmetal=2.00J/g°C and CH2O=4.186J/g°C. The hot metal is placed in the cool water. What is the final temperature of the metal once it comes into thermal equilibrium with the water.

As a system increases in volume, it absorbs 52.0 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.597 atm. The final volume of the system is 58.6 L. What was the initial volume of the system if the internal energy of the system decreased by 106.2 J? Volume =  L

A piece of titanium metal with a mass of 21.6 g is heated in boiling water to 99.5 °C and then dropped into a coffee-cup calorimeter containing 75.0 g of water at 21.8 °C. When thermal equilibrium is reached, the final temperature is 24.5 °C. Calculate the specific heat capacity of titanium. (The specific heat capacity of liquid water is 4.184 J/g. K.) Specific heat capacity= J/g. K

A 149.2-g sample of a metal at 74.4°C is added to 149.2 g H20 at 15.5°C. The temperature of the water rises to 18.6°C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the water. The specific heat capacity of water is 4.18 J/°C g.

A student is attempting to determine the heat capacity of a Styrofoam cup calorimeter by pouring hot water into a Styrofoam cup containing cold water. The student determined the mass of the cold water to be 21.2455 g and its initial temperature to be 20.36 °C. The mass of the hot water was 24.2646 g and its initial temperature as 34.54 °C. The final temperature of the water after mixing was determined to be 24.57°C. The specific heat capacity of the water is 4.184 J/(g•°C). What is the heat capacity of the Styrofoam cup calorimeter? Assume the temperature of the calorimeter is the same temperature as the cold water. 4.184 J/°C 132.5 J/°C
