Not all materials stretch the same way when you heat them up. This is called thermal expansion, and it can be very different depending on the type of material.
Here are some important points to know:
Type of Material: Generally, metals expand more than things like ceramics or glass. For example, aluminum gets longer by about 0.022 mm for every meter when the temperature goes up by 1 degree Celsius. In comparison, glass only stretches about 0.009 mm for the same temperature increase.
Temperature Change (ΔT): The amount a material expands also depends on how much the temperature changes. If you heat an aluminum rod by 100 degrees Celsius, it would stretch about 2.2 mm for every meter.
In short, different materials react to heat in their own ways because of their special thermal expansion properties.
