Sagot :
Answer:
Glass expands less than steel when heated. This is because of the coefficient of expansion. The statement is true.
Explanation:
Thermal expansion refers to:
- Expansion of the size of an object, when heat is provided to that object, is called as thermal expansion basically it is expansion due to heat
Coefficient of thermal expansion:
- (CTE) refers to the rate at which a material expands with increase in temperature.
given that lid on the jar is made up of steel.
so when we very hot water run over the lid for short time, The metal lid expands but the glass jar. which forms a gap between the metal lid and the glass jar.
Coefficient of thermal expansion of ordinary glass is 8.6×10^-6/°
Coefficient of thermal expansion of steel is 13×10^-6/°
we can say that
Steel having higher coefficient of expansion will expand more as compared to the glass.
Hence the statement is True.
