A 43.0-g sample of copper at 99.9 °C is dropped into a beaker containing 149 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.) Final temperature = How much energy is required to raise the temperature of 14.7 grams of gaseous hydrogen from 24.7 °C to 37.7 °C ? Answer: Joules.

A 30.5 g sample of copper at 99.8 °C is carefully placed into an insulated container containing 207 g of water at 18.5 °C. Calculate the final temperature when thermal equilibrium is reached. Assume there is no energy transferred to or from the container. Specific heat capacities: Cu =0.385 Jg-loc- H20 - 4.184 Jgloc!

Part A State the law of conservation of energy The law of conservation of energy states that energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms. The law of conservation of energy states that energy can not be created but it can be destroyed. Energy can be transferred from one object to another can be destroyed in a chemical reaction, and it can assumo different forms The...
