K.C.S.E Physics Q & A - MODEL 2016PP1QN07

Figure 5 shows an aluminium tube tightly stuck in a steel tube.

Explain how the two tubes can be separated by applying a temperature change at the same junction given that aluminum expands more than steel for the same temperature rise.

answer

By cooling
Aluminium contracts more than steel for the same temperature range
