Imagine that a full 500 mL bottle of water (d = 0.9998 g/mL) sitting in your car during the summer went from 15.0 degree C to 20 degree C. Assuming that the same amount of energy went into a 150.0 gram seatbelt (S_h = 0.85 J/(g K)) what would the temperature be in Celsius, if the seat belt was originally at 18 degree C? Write the reaction for the enthalpy of formation reaction of iron (III) dichromate. Calculate the enthalpy...

Imagine that you fill a glass Coke bottle half-full of water and blow over the top. Remember the pitch. Tap the side of the bottle with a metal object (such as a table knife) and remember that pitch. Add more water to the bottle and try again. The pitch of the sound you hear when you blow over the top is higher than it was when the bottle was half full; the pitch you hear when you tap is lower....
