Does water expand when it's heated

WebBelow 4°C, the hydrogen bonds between water molecules become stronger and cause the matter to expand. Because the bonds between water molecules are stronger,... WebIn a few cases, heat actually makes some things contract rather than expand. The best example is water. When ice is heated from 0 to 4 degrees C, it actually contracts. The water molecules get closer together and the water occupies less volume. However, above 4 degrees C water expands as it is heated like most other liquids.

WebWater does expand with increasing temperature (its density decreases) at temperatures greater than 4 ° C ( 40 ° F). However, it is densest at + 4 ° C and expands with decreasing temperature between + 4 ° C and 0 ° C ( 40 ° F to 32 ° F ), as shown in Figure 1.8. A striking effect of this phenomenon is the freezing of water in a pond. WebExample - water is a liquid where the volumetric expansion coefficient changes a lot with temperature.
