Density equals mass divided by volume

Density equals volume divided by mass

Density equals mass multiplied by volume

Density equals mass plus volume

Measure its longest side with a ruler and then cube that single length value

Lower it into water and measure the volume of water it displaces

Weigh it on a balance and read the mass straight off as the volume figure

Measure its temperature with a thermometer and convert the reading to volume

Only the kinetic energy of its particles, ignoring any potential energy stored

The energy that must be supplied to melt it completely from a solid into a liquid

The total kinetic and potential energy of all its particles

The heat lost to the surroundings as the substance gradually cools down again

The energy needed to change the state of one kilogram of it without any temperature change

The fixed temperature in degrees Celsius at which the material starts to melt

The mass in kilograms of exactly one cubic metre of the material

The energy to raise the temperature of one kilogram by one degree Celsius

The energy supplied increases the potential energy of the particles to break bonds, not their kinetic energy

No energy is being supplied to the substance at all while it is in the middle of melting

The thermometer is simply faulty and cannot register the steadily rising temperature of the solid as it continues to melt

The particles stop moving completely once the solid reaches its melting point temperature

It increases, because liquid water takes up more space than solid ice

It stays the same, because mass is conserved

It decreases, because some particles escape as the ice turns to water

It depends on the temperature of the room while the ice is melting

Because a brand new substance is made when the particles rearrange themselves

Because it always releases a gas that bubbles out of the original material

Because no new substance is made and the change is reversible

Because it cannot be reversed once the substance has changed its state

The weight of the gas pressing down on the base of the container

The container slowly shrinking inwards and squeezing the gas inside

The gas particles sticking firmly to the inside surface of the walls

The gas particles colliding with the walls

The particles move faster, so they hit the walls more often and harder

The individual gas particles swell up and get noticeably bigger when heated

Extra gas particles are created out of the heat energy supplied to the gas

The sealed rigid container expands to make room for the heated gas inside

The liquid becomes much denser the deeper down into it you go

There is a greater weight of liquid above pushing down

The liquid gradually gets warmer and warmer the deeper down you go

The container is always narrower at the bottom than it is at the top
