effect of heat expansion of matter

A small gap is provided between the rails on railway tracks to make provision for the expansion of rails during summer, otherwise, the rails may bulge due to expansion causing train accidents. If a metal wire is used in a pendulum, its length changes with temperature. Durin..

Matter expands on heating, i.e., solids, liquids and gases expand on heating. Let us consider expansion of solids: Three types of expansions are considered in case of solids. This classification is done according to the shape of the solid..

Heating Effect of Electric Current - Energy exists in various forms such as mechanical energy, heat energy, chemical energy, electrical energy, light energy and nuclear energy. According to the law of conservation of energy, energy can be transformed from one form to a..

When we heat a solid, we add energy to the system increasing the vibration of the particles. Eventually these particles break free from their binding forces and melt. The normal melting point of a crystal is the temperature at which it melts under one atmospheric pressure. Increase ..

We heat raw food to soften it. We freeze water into ice by cooling it in refrigerator. When we boil water in a kettle we observe the steam oozing from the mouth of the kettl..

Effect of Temperature on Matter..

Pressure has little effect on the state of solids and liquids as the inter-particle distance is already minimized in these situations. However, the effect of pressure in case of gases is considerabl..
