- 1what is the equation for densitymass / volume
- 2what is the arrangement of a solid likestrong forces of attraction hold the particles tightly together, can only vibrate, in a regular structure
- 3what is the arrangement of a liquid likeweaker forces of attraction between the particles, can move past each other, irregular structure
- 4what is the arrangement of a gas likealmost no forces of attraction between the particles, travel at high speeds in any direction, less dense than the others
- 5how can you find the density of a regular soliduse a balance to measure its mass, measure length x width x height, use formula to calculate density
- 6how can you find the density of an irregular soliduse a balance to measure mass, submerge it in a eureka can filled with water, water displaced goes in measuring cylinder, record volume of displaced water, use the formula to find density
- 7how can you find the density of a liquidput a measuring cylinder onto a balance, add 10ml of liquid each time and record mass, do until MC is full and then calculate density for each measurement, then calculate average of all densities
- 8what does internal energy meanthe total amount of energy stored in an objects kinetic and potential energy stores
- 9what does heating a system do the an objects internal energyit increases
- 10how does a change in state occurwhen the object is heated so the bonds between the particles break / when frozen the particles form bonds
- 11what state change is solid to liquidmelting
- 12what state change is liquid to solidfreezing
- 13what state change is liquid to gasevaporting
- 14what state change is gas to liquidcondensing
- 15what state change is solid to gassublimating
- 16true or false - change of state conserves masstrue
- 17what is the definition of specific latent heatthe amount of energy needed to change the state of 1kg of a substance
- 18what formula links specific latent heat, mass and energyenergy = mass x SLH
- 19what is the unit for specific latent heatJ/kg
- 20how are the temperature of a gas and the average energy in the kinetic store relatedas one increases the other increases (directly proportional)
- 21what is pressure (in terms of particles)when the particles are in a volume, they collide and hit the side of the container which exerts a force
- 22true or false - pressure and volume are directly proportionalfalse - they are indirectly proportional
- 23what equation links constant, pressure and volumeconstant = pressure x volume
- 24what is the unit for pressurePa (pascals)
- 25how can a change in pressure change the volume of the containerthe forces from inside the container are equalled by the forces outside of the container, when these become unequal the volume changes / the object changes shape
