Namr the type of thermal expansion that occur in solid, liquid and gases
Answers
The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been observed that bottles which are tightly sealed with a metallic lid are easily opened when the bottle is kept upside down in a hot water for some time in such a way that just the lid is immersed in water. In this way metallic lid expands and opens easily. Also the level of mercury rises in thermometer when it is put in warm water and when the thermometer is taken out the mercury level drops.
Answer:linear expansion, areal expansion and volumetric volume.
Explanation:
Thermal expansion refers to the expansion or contraction of the dimensions of the solid, liquid or gas when their temperature is changed. There are three types of thermal expansion depending on the dimension that undergo change and that are linear expansion, areal expansion and volumetric volume.
