rrangement) Particles become further apart / more space between particles in a gas / no longer in contact with each other / move over a larger space (Movement) Move faster / more kinetic energy

Match the description to the state

Note some descriptions describe more than one state.

Note (aq) means dissolved in water.

Apparatus

Method

1. Measure the mass of the water and beaker with a mass balance
2. Add potassium chloride until no more will dissolve
3. Calculate the mass of salt using mass of salt water in beaker - mass of water in beaker
4. Measure the mass of the salt solution with a mass balance
5. Finally Repeat the experiment using different temperatures of water.
6. First Measure 100 cm3 of water using a measuring cylinder
7. Measure the temperature of the water with a thermometer
8. Add the water to the beaker

Magnesium oxide (MgO)

Carbon monoxide (CO)

Water (H2O)
