Test Nine

1. Thermal energy is all the energy and object has. Heat is a type of energy in which it is transferred from an object with a higher temperature to an object with a lower temperature. So thermal energy includes the heat in an object and that is how they are related. The temperature of an object is the average amount of energy. When heat is transferred to an object the temperature will often go up as the atoms and molecules start to move faster. Thermal energy is related to this because it includes the temperature of an object as well.
2. Some objects get hot more quickly than others because they are smaller in size and volume. Also it depends on the specific heat of an object. Some are higher than others and therefore they need more energy to be heated up which takes a little longer.
3. The three different types of heat transfer are conduction, radiation and convection.Conduction is when atoms get warmer they start to move faster and collide with one another, conduction is the energy created by theses collisions. Radiation is when energy is is transferred in the form of electromagnetic waves. It is also know as light. And finally convection is when heat moves in waves of a fluid.
4. 209,000J is the specific heat required to raise 5 kg of water to 10 k.
5. If I were camping on a mountain I would build a tent and make a fire as both would get and keep me warm sufficiently. To get warmer first I would build a fire and heat transfer would occur between me and the fire because of radiation. The energy from the fire would transfer to my body through electromagnetic waves. After that I would go in my tent which would act as an insulator for me, after all it is pretty much made out of paper. I might even bring a heater to put in my tent. If it were metal it would serve as a conductor.
