Temperature : On increasing the temperature of solids, the kinetic energy of the particles increases.Due to the increase in kinetic energy, the particles start vibrating with greater speed.The energy supplied by heat overcomes the forces of attraction between the particles. The particles leave their fixed positions and start moving more freely. A stage is reached …
Matter around us exists in three different states– solid, liquid and gas. These states of matter arise due to the variation in the characteristics of the particles of matter. THE SOLID STATE All solid have a definite shape, distinct boundaries and fixed volumes, that is, have negligible compressibility. Solids have a tendency to maintain their …
Characteristics of Particles of Matter i ) PARTICLES OF MATTER HAVE SPACE BETWEEN THEM Particles of one type of matter get into the spaces between particles of the other. Particles of matter are continuously moving, that is, they possess the kinetic energy. As the temperature rises, particles move faster. So, we can say that with …
The amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point is known as the latent heat of fusion.
heat energy is absorbed by ice without showing any rise in temperature, it is considered that it gets hidden into the contents of the beaker and isknown as the latent heat
Kelvin is the SI unit of temperature, 00 C =273.15 K.
The process of melting, that is, change of solid state into liquid state is also known as fusion.
The melting point of ice is 273.15 K .
For water this temperature is 373 K (100 0C = 273 + 100 = 373 K).
