Explanation of thermal expansion of a substance
By: Andrew Smith - 514754
When explaining thermal expansion of a substance it is helpful to understand that, at least to my knowledge, there are two types of thermal expansion: Linear and Volumetric. Linear expansion is what happens when you have a solid rod of any one substance, for...
The solid matter with the lowest density
By: Jacob Stanley
