Do Some Science
1. Define the following terms using your textbook: temperature (with respect to kinetic energy), thermal energy, heat, thermal conductivity, thermal equilibrium and Newton's Law of Cooling. What dictates the direction of thermal energy transfer between two objects?
2. Watch the following diffusion experiment. There are equal amounts of warm water and cool water. Red dye is placed in the warm water, and blue dye is placed in the cool water. Which has faster diffusion? Explain using the definition of temperature you found in your textbook.

3. If you touch a piece of copper that has been sitting on a desk in a room for a really long time, it will feel cool in your hand. Yet, it is the same temperature as the room's. Explain what is happening between your hand and the copper based on thermal energy transfer and thermal conductivity of the copper.
4. If you touch a piece of wood that has been sitting in the same room, it will not feel as cool in your hand as the copper did. Yet, it is also the same temperature as the room's. Explain why the wood feels warmer than the copper based on thermal energy transfer and thermal conductivity of the wood.
5. Explain why the copper and the wood (and basically anything in a normal room) have reached thermal equilibrium with the room's temperature over a long period of time.
6. Give your own example of two objects that have different initial temperatures, but eventually reach thermal equilibrium. Explain using thermal energy transfer principles.
7. When you touch a pot at 100 degrees F, you will feel less pain than you would if you touch a pot at 400 degrees F. Explain using Newton's Law of Cooling.
