The coefficient of thermal expansion of metal is ___ compared to ceramic?

much lower than
slightly lower than
the same as
slightly higher than

The correct answer is: slightly higher than

The coefficient of thermal expansion of metal is slightly higher than ceramic. This means that metal will expand slightly more than ceramic when exposed to the same amount of heat. Options A and B state that metal has a lower coefficient of thermal expansion compared to ceramic, which is incorrect. Additionally, option C states that both metal and ceramic have the same coefficient of thermal expansion, which is also incorrect.
