Heat

Heat is energy that flows from

Heat is energy that flows from a hotter body to a colder body. Temperature shows how hot or cold a body is. Equal amounts of heat can raise the temper

During melting

During melting, ice changes into water at 0°C without a rise in temperature. The heat absorbed at this constant temperature is called latent heat of f

During boiling

During boiling, water changes into steam at 100°C without a rise in temperature. The heat absorbed at this constant temperature is called latent heat

The melting point is the constant

The melting point is the constant temperature at which a solid changes into liquid. The boiling point is the constant temperature at which a liquid ch

When pressure is applied to ice

When pressure is applied to ice, its melting point becomes lower than 0°C, so ice melts. When the pressure is removed, the melting point returns to 0°
