particle model remote revision

what process describe the change of a substance from a liquid to a gas?

• condensation

• liquidation

• distillation

• evaporation

particles in a solid.......Tick all the boxes which apply

• are held together by strong forces of attraction

• are weaker than a liquid

• vibrate around a fixed position

• have a regular lattice structure

Particles in liquids are best describe as.....(tick all boxes which fit)

• having a fixed position

• having moderately weak forces of attraction between them

• take the shape of a container

• able to move

to turn a solid into a liquid you need to

• break bonds between the particles

• make bonds between the particles

gas particles move....tick as many which apply

• in random directions

• at a range of different speeds

• at faster speeds compared to liquids

• slowly around a fixed point

how does temperature affect gas pressure

• it gives it more energy

• it causes it to go up

• as temperature increases pressure can increase if the gas is in a fixed container

• the gas pressure of the particles decreases when temperature increases

what types of particles have the most kinetic energy

• particles at a low temperature

• high pressure

• solid particles

• gas particles

what is the equation that links mass, volume and density

• density = mass x volume ²

• density = mass x volume

• density = 1/2 mass x volume

• density = mass / volume

what is the best definition of density

• how much mass of a substance we have per unit volume

• the volume of a substance we have per mass in kg

• how squashed together an object is

how do you calculate the volume of an irregular shape?

• measure it with a ruler by using length x width x depth

• find the volume of water the shape displaces

• find out how much of it you can fit in a measuring cylinder
