P6: Molecules and Matter Flashcards
What is the equation to work out density
Mass/Volume
What is the correct standard unit of density
kg/m3
Kilograms per metres cubed
How do we work out internal energy
Combine the kinetic energy with the potential energy
What happens as we increase internal energy
Both kinetic energy and potential energy increase. This causes a temperature rise
What happens if we heat something
More energy is transferred
What is it called when particles in a substance are constant
Brownian Motion
How do we work out specific heat capacity
Energy / (Temperature X Mass)
What is specific heat capacity measured in
J/Kg 0 c
Joules per kilogram degree Celsius
What is specific latent heat of fusion
Amount of energy needed to turn a solid into a liquid
What happens if increase the temperature of a gas
If we have a container full of gas, as temperature increases, pressure increases
What is density
The mass per unit volume of a substance
How do we work out the volume of a regularly shaped object
Width X Height X Depth
What is everything made of
Particles
What is internal energy
The total energy stored by particles of a substance
What is the specific latent heat of vaporisation
Amount of energy needed to turn a liquid into a gas
