thermal expansion in solids

What does this diagram indicate?Why do we call it as a particle diagram?

What did you infer from the above experiment?

Learning Objective:Students will be able to analyse the real life examples of thermal expansion in solids.

Would you drive a train down these train tracks? Why?

Group Activity

Consider the buckled railway lines from the earlier slide and propose a solution to this problem

Two rods A and B of the same metal, but of length 1 m and 2 m respectively, are heated from 0°C to 100°C then A. both the rods A and B elongate the same B. the rod A elongates more than the rod B C. the rod B elongates more than the rod A D. the rod A elongates, but the rod B contracts
ASSET QUESTION

Summarise what you have learnt now.

ASSESSMENT

Cite an example of thermal expansion that can be seen in the kitchen.

homework
