Review | Constants Periodic Table Part A Calorimetry is a method used to measure changes in enthalpy, or heat, that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant volume or "bomb") calorimeters. Bomb calorimeters are used to measure combustion and other gas- producing reactions, in which the reaction is observed in a strong, sealed vessel. A simple constant-pressure calorimeter can be made from a foam coffee cup and a thermometer, in which energy changes in a...

You have purchased a portable resistive water heater, consisting of a resistor R = 3.5 Ω connected to a 12 V outlet in your car. On a cold-weather camp-out you want to warm up some water that has been left out over night for your morning tea. Assume the water is in an insulated cup so no heat is lost to the surroundings. You end up with 0.75 L of liquid water at a final temperature of 65 oC. How...
