Answers
thermal expansion, the general increase in the volume of a material as its temperature is increased. .
in solid three states of matter (solid, liquid and
gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. When a solid is heated, its atoms vibrate faster about their fixed points. ... An increase in temperature results in the expansion of the liquid which means it rises up the glass.
in liquid. three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does. When a solid is heated, its atoms vibrate faster about their fixed points. ... An increase in temperature results in the expansion of the liquid which means it rises up the glass.
Answer:
1Ans Thermal expansion, the general increase in the volume of a material as its temperature is increased. ... If it is not isometric, there may be different expansion coefficients for different crystallographic directions, and the crystal will change shape as the temperature changes.
2Ans Thermal expansion can be defined as the change in the length, width, height, or volume of any material on changing the temperature. Thermal expansion is very evident in solids as atoms are densely packed. Thermal expansion of solids has loads of applications in day to day life.
3Ans Increase in dimensions of a liquid on being heated is called thermal expansion of the liquid. Types. Liquid has only volume. When heated, its volume increases.
