level questions: Specific Heat Capacity/Specific Latent Heat

QuestionAnswer
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]
