- Physics
- density = mass/volume
- density is how heavy something is for its size
- Change of state
- solid
- don't compress
- vibrate on the spot
- conducts
- doesn't move or flow
- gas
- flows
- matches container
- compresses
- liquid
- cannot compress
- matches whatever container
- flows
- solid
- don't compress
- vibrate on the spot
- conducts
- doesn't move or flow
- liquid
- cannot compress
- matches whatever container
- flows
- solid
- volume and temperature of gas
- if you increase the temperature of a gas, you transfer energy into kinetic energy stores of particles.
- the higher the temperature the higher the kinetic energy
- this makes the particles expand, when it cools the particles shrink
- the temperature of a gas is related to the average energy in the kinetic energy stores of the particles in the gas.
- the higher the temperature the higher the kinetic energy
- this makes the particles expand, when it cools the particles shrink
- the higher the temperature the higher the kinetic energy
- the higher the temperature the higher the kinetic energy
- the temperature of a gas is related to the average energy in the kinetic energy stores of the particles in the gas.
- if you increase the temperature of a gas, you transfer energy into kinetic energy stores of particles.
- internal energy
- internal energy of a system is the total amount of kinetic and potential energy in its particles energy stores.
- specific latent heat
- is the amount of energy needed to change the state of a 1kg mass
- energy= mass x specific latent heat
- energy= mass x specific latent heat
- is the amount of energy needed to change the state of a 1kg mass
- density = mass/volume
