So heating a Substance results in What [Energy] | -Increases the amount of Energy, found in the Thermal Energy Store [Kinetic Energy Store] |
Kinetic Theory says Temperature can measure what? | -Temperature can measure the Average Internal Energy of an Substance |
What is the Specific Heat Capacity of a Substance? | -This is simply the change in Energy of the Substances Thermal Energy to store, to raise the Temperature of 1kg, by 1 degree Centigrade. |
Formula, to find out the Specific Heat Capacity? | Change in Thermal Energy [J] = Mass [kg] x Specific Heat Capacity x Change in Temperature [oC] |
How can you find the Specific Heat Capacity of a Substance? | -For a Liquid, or Solid, its the Same
-Use a Mass Balance, to get the Mass of your Substance
-Simply have a Power supply connect to a Heater, that would heat up the Liquid/Solid
-Have a Thermometer, to keep the Track on the Temperature.
-Every 10 degrees, stop the Experiment and Record the Energy on the Joulemeter
-Repeat it all by 3 Times, top get a Mean
-Watch out for some errors, like Heat Escaping. This can be solved however from Insulation, and Lids |
When a Substance is Melting, and you keep Heating the Solid up, does the Temperature Increase? | -No. The Energy that is being transferred is put into the Bond Breaking between the Particles.
-They would make Flat Spots on a Heating Graph |
When a Substance is Condensing, and you keep Cooling the Gas down, does the Temperature Decrease? | -No. The Substance is Forming Bonds that give out Energy |
What exactly is the Specific Latent Heat? | -This is the Change of Energy in its Thermal Energy Store, when 1 Kg of the Substance Changes state, without Changing its Temperature |
What is Specific Latent Heat of Fusion? | -This is the Specific Latent Heat, between a Solid and Liquid |
What is the Specific Latent Heat of Vaporisation? | -This is the Specific Latent, between a Liquid and Gas |
What is the Formula for Specific Latent Heat? | Thermal Energy for a Change in State [J] = Mass [kg] x Specific Latent Heat [J/kg] |
