This is especially true when you have very tight tolerances (such as ± 0.0001″, or ± 0.0025 mm) and heat expansion results in either metal parts failing inspection or ...
WebOct 11, 2009 · Answer. Usually, when things freeze - in other words turn from a liquid into a solid - they shrink or get smaller. This is because, normally, if you make something hotter, it vibrates more. When it vibrates more, it tends to take up more space, so it tends to expand. So, logically, if you cool something down, then the particles should move more ... WebIn general though, heat makes solids, liquids, and gasses expand.
