Gas thermal expansion 1 - physics experiment

http://www.fizik.si The air in the container and the balloon extends during heating. The balloon also gets bigger. When the air is cooled down, its volume decreases and so decreases also the volume of the balloon. This is physics experiment for science project. http://www.fizik.si Zrak v posodi in balonu se s segrevanjem širi.

Thermal expansion is the tendency of matter to change in volume in response to a change in temperature , through heat transfer

This is a video of an experiment that we had done before on solids expansion.

The expansivity of the components of the mixture can cancel each other like in invar.

The thermal expansivity of a mixture from the expansivities of the pure components and their excess expansivities follow from:
