When energy is added to matter its temperature will rise. The temperature rise will depend on the mass which in turn depends on its density.

How do the particles in a solid move?

Randomly in all directions

They roll over each other

They vibrate around a fixed point

What is the equation for density?

Mass × volume

Volume ÷ mass

Mass ÷ volume

The density of iron is 7.8 g/cm^{3}. What is the mass of 5 cm^{3} of iron?

1.56 g

0.64 g

39 g

What is the density of a rock if it has a mass of 1,500 kg and a volume of 0.5 m^{3}?

750 kg/m^{3}

3,000 kg/m^{3}

7,500 kg/m^{3}

What is the mass of 15 cm^{3} of a substance that has a density of 50 g/cm^{3}?

750 g

0.3 g

3.33 g

How much energy is needed to raise the temperature of 500 g of lead by 10°C? (c = 129 J/kg°C)
