1 discuss how a grandfather clock a pendulum clock accurate, Ask an Expert

Academics

1. Discuss how a grandfather clock (a pendulum clock), accurate at 20oC, will run fast or slow on a hot day (say, 30^oC)?

Knowing this, what other things in your home will run differently based on temperature?

Thermodynamics

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.
