1. Discuss how a grandfather clock (a pendulum clock), accurate at 20oC, will run fast or slow on a hot day (say, 30oC)?Knowing this, what other things in your home will run differently based on temperature?
2. Discuss how the conservation of energy law explain whys the temperature of a gas increases when it is quickly compressed, whereas the temperature decreases when the gas expands.Give an example of where you would see this law in practice in your everyday life.
