The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion the change in size or volume of a given mass with temperature Hot air rises because its volume increases which causes the hot air s density to be smaller than the density of surrounding air causing a buoyant upward force on the hot air
Once you get that the definition of the coefficient of linear expansion is easy to follow It is the length expansion per unit length suffered by a body when its temperature is raised by $1K$ So if you have a rod of length $1m$ then the amount by which it expands when you heat it by $1K$ is its coefficient of linear expansion
