What is the kinetic particle model?Show answer
All matter is made of tiny particles (atoms or molecules) that are constantly moving. The hotter the substance, the faster the particles move on average. The state of a material depends on how strongly its particles are held together and how much energy they have.
What is q1?Show answer
Describe the arrangement and motion of particles in a gas. [2 marks]
What is q2?Show answer
Name the change of state from liquid to solid and from gas to liquid. [2 marks]
What is q3?Show answer
Use the particle model to explain why a solid keeps its shape but a liquid does not. [2 marks]
