Give the state of matter where particles slide over eachother
Draw the arrangement of particles in a solid
State the piece of equipment used to accurately measure the mass of a liquid.
Calculate the density of an object with a volume of 10cm3 and a mass of 3kg
Challenge: Substance X has a mass of 85kg and a length of 5cm, height of 3cm and width of 9cm. Calculate the density.
Why is a change of state a physical change?
Recall the 5 changes of state
Describe what happens to the arrangement, motion and bonding of particles during FREEZING

Describe what happens to the arrangement and motion of particles during CONDENSING
Particles are vibratin in a fixed position.
Particles move in random directions quickly
Particles change from bvibrating to sliding over each other.
Some bonds break between particles .
All bonds break between particles and particles go from a regular arrangement ro an irregular arrangement.
Describe the arrangement and movement of particles in a solid.
Describe the arrangement and movement of particles in a liquid.
Describe the arrangement and movement of particles in a gas.
Substance turns from a gas into a liquid
Particles form lots of bonds and form a regular arrangement
All bonds break and particles change from sliding over each other to moving quickly in all directions.
