Homework 9

Objective 1
1. Celsius, kelvin, fahrenheit
2. Temperature is the measure of thermal energy and heat is created by thermal energy. Craig helped
3. It means the object is very heated so it raises the temperature.
4.your hand gives off heat and makes the ice cube warmer because the energy is transferred.
5.Some objects are more conducive to heat than others.
Objective 2
1. With mecury that expands or contracts according to heat.
2.All of them calculate by how much matter and how fast the particles are moving inside of the object.
3. 5.0 celsius is 41 farehnight.http://www.google.com/search?hl=en&client=safari&q=what+is+5.0+celcus+to+farhenith&aq=f&aqi=m1&aql=&oq=&gs_rfai=
4. 460 degrees in celsius
5. 209000joules
Objective 3
1. Radiation, Conduction, Convection
2. Heat rises
3. conductor help heat move out and insulator hold heat in
4. A copper pipe would work better as a conductor because it transfers heat best
5. I would put up a tent, then build a fire close to the tent, the tent would use convection after you got in it because the heat would be trapped and start to move around in the tent. The fire would help to warm the tent if the fire was close enough to give heat to the tent but not close enough to burn the tent this would be using radiation to help get heat waves through the outside of the tent.
Objective 4
1.Tempature and pressure cause matter to change state
2. The particles get excited and expand therefore creating thermal energy
3. It stays the same because only particles are expanding or condensing and getting close to each other.
4. Its particles are heated up and they expand therefore going into the liquid state.
5.The water inside will start to expand and boil therefore wanting to let out steam and when you dont let the steam out by poking holes it will blow up.
Objective 6
Will be turned in for Mr. H to look at.
