What I have learnt:
I have learnt that when a matter is heated, the reason it expands is because its speed increases and not the increase in size. I can now clearly understand how matter expands in a more detailed way. I learnt that, from the kinetic model of matter, tiny particles that make up matter are always in continuous motion. I understand more fully why gas can be compressed but liquid and solid cannot.
Questions I have:
1) Does the rate of collision increase or decrease when the matter is heated?
2) Does gas or solid expand more?
3) Why isn't the answer 'molecules move further apart when heated' accepted but 'molecules move more quickly when heated' is? Why isn't the first answer correct?
4) Are smoke particles considered as gas particles?
5) Are smoke particles faster moving compared to air molecules?
