1.4 Heat Flashcards
What are the symbol and unit of temperature?
T and degrees celsius
What is temperature?
How hot or cold an object is.
What is heat energy?
A form of energy.
What is specific heat capacity?
The heat energy required to change temperature by 1kg mass by 1degree celsius and it takes into account the type of substance.
What are the symbol and unit of specific heat capacity?
c and joules per kilogram degrees celsius (J/kg^0C)
What is the equation of specific heat capacity?
Eh=cm(changeinT)
heat energy equals the specific heat capacity times mass times change in temperature.
What is the relationship between changing state and temperature?
When there is a change in temperature there is no change in state.
What is specific latent heat?
Heat energy required to change state of 1kg mass with no change in temperature taking into account type of substance.
What are the unit and symbol of specific latent heat?
l and joules per kilogram(J/kg)
What is the equation for specific latent heat?
Eh=lm
heat energy equal specific latent heat times mass.
What is vaporisation?
Change from gas to liquid or liquid to gas
What is fusion?
change from solid to liquid or liquid to solid.
