WebSep 4, 2024 · Does heat or cold make things expand? Most matter expands when heated and contracts when cooled, a principle called thermal expansion. The average kinetic energy of the particles increases when matter is heated and this increase in motion increases the average distance between its atoms. WebFeb 3, 2024 · A. Foster Lyons, an engineer and building-science consultant, responds: The short answer is because hot-water pipes aren’t attached to toilets, which help reduce the number of burst cold-water pipes. Here’s why. Water expands when it freezes, increasing in volume about 9% from its liquid state. That’s why ice floats—it’s less dense ...

WebAug 31, 2011 · 15. your question is about large drops in pressure, and why they cool gasses. The answer is that the gas is doing work in the process of expanding, and this work releases energy to the environment. If you prevent the gas from doing work, if there is nothing for it to push against, it doesn't get cold.

So (273+40)/ (273+20) = 1.0689 so 6.89% increase. 1 bar = 14.5 psi. So 100/14.5 = 6.89. allie rapsey realtor
