Thermal Expansion and Thermal Contraction

Watch demos of thermal expansion and contraction. Metal ball and ring demo shows how solids expand when heated and then contract when they cool. Liquid in a test tube expands up the glass straw when heated similar to how a thermometer works. A balloon on a jar expands and contracts when placed in hot and cool water.
Learn why solids, liquids, and gases expanded and contract by learning about the kinetic energy of the particles. As temperature increases, the particles speed up and gain kinetic energy. This causes them to collied with each other with more force, and therefor push each other farther apart causing expansion. The reverse is true when the substances cool and the particles slow down, losing kinetic energy.

excellent

thanks!

[@SonakshiGouraha]

liked the use of experiments and the molecular motion sticker right next to it, great way of proving theory in a practical form and integrating both. tysm!

[@pointsourcescience7512]

Thank you very much!

[@reshaligovender8566]

Thank you this really helped me a lot.

[@sugarclouds2426]

I love the first example, new sub, keep going with that examples!❤go go go 😂😂

[@pointsourcescience7512]

will try to!

[@nourazorom4128]

Thanks a lot i have a test tommorow :) and this vid really helped

[@EbrahemElwer]

Wonderful ❤

[@hahayes.4595]

Love the explanation!

[@pointsourcescience7512]

Glad it was helpful!

OMG, I've learn a lot from the first example, im gonna use it in my life

[@abdelrahmanarafeh2107]

thank you, I found the vedio that I want
