1.) Imagine you have 1.00 kg each of iron, glass, and water and that all three samples are at 10 C. a.)Rank them from lowest to highest temperature after 100J of energy (Q) is added to each. b.) Rank them from lowest to greatest amount of energy transfer by heat if each increases in temperature by 20 Degree C. (hint: specific heat, c, of iron:448 J/KG.C, of glass:837J/Kg.C, of water: 4186 J/Kg.C)

2) The temperature of a 0.0500 kg ingot of metal is raised to 200C and the ingot is dropped into a light, insulated beaker containing 0.400 kg of water initially at 20 C. If the final equilibrium temperature of the mixed system is 22.4 C , find the specific heat of the metal. (hint: and c of water : 4186 J/Kg.C.)

3) Consider an ideal gas under compression. If as the gas is compressed volume decreases, what happens to pressure and temperature. Explain and show the equation as discussed in lab.
