Describe the process of thermal expansion?

Answer 1

Closed-loop piping systems are used extensively to circulate heated or cooled water (or other liquid) to provide heating and cooling for buildings. The problem is that the liquid filling the pipe is not compressable. When the temperature increases, the liquid expands, and can burst pipes and coils, wreck pump seals, and generally wreak havoc. The solution is to plumb a tank filled with air into the system. Sometimes there is a rubber bladder separating the water from the air, sometimes not. Either way, when the water expands, it flows into the tank, compressing the air instead of wrecking something. It gets it's name from the fact that the expansion of the liquid is caused by heat, thus thermalexpansion tank.

Answer 2

Thermal Expansion is the increasing of volume due to heating of a body. in rare cases a body has negative thermal expansion coefficient i.e body expanding on cooling too (like water at 4C). But in general body expands on heating.

This happens because on heating i.e. increasing the temperature increases the mean kinetic energy possessed by individual atoms or molecules. Due to this extra energy they move apart from each other, i.e this energy somewhat overcomes the bonding energy in between them so they move little apart. This results in overall expansion of the body.

Answer 3

the process of thermal expansion is the increase of volume resulting from an increase in temperature

Answer 4

thermal explanation is changes in matter due to heat
