level questions: Specific Heat Capacity
Question | Answer |
---|---|
what is heat? | a form of energy transfer in joules |
how is heat transferred | from a hot place to a cooler place through conduction, covection or radiation |
what is temperature? | a measure of the average kinetic enrgy of the particles in an object in degrees celcius or Kelvin |
describe what happens to the particles in an object when heat energy enters it | particles move quicker and their average kintetic energy increases. Therefore, their temperature increases |
what is specific heat capacity? | the amount of energy needed to raise the temperature of 1kg of substance by 1 degree celcius, masured in Jkg−1∘C−1 |
what is the formula for specific heat capacity | Eh=cmΔT where Eh is heat energy in joules c is specific heat capacity m is mass in kg ΔT is change in temperature |
