1. Physics Revision- CHAPTER 3 – Particle model of matter
Density is the mass per unit volume of a substance.
Write down the equation that you would use to calculate density.
A block of ice has a mass of 0.25kg and a volume of m3. Calculate its density. :
Fill in the diagram and label the arrows:
Solid Liquid Gas
When the gas in a container with a fixed volume is heated, the pressure increases as the temperature increases.
Explain why the pressure increases.
The diagram below shows evaporation. Explain how the temperature of the liquid in the container decreases as the liquid evaporates.
Label the temperature time graph for water:
What is specific heat capacity?
What is specific latent heat?
