melting
A solid becomes a liquid when it temperature has reached its Melting Point (also called it Point of Fusion.)
melting point. :)
The boiling point refers to the temperature at which a substance transitions from a liquid to a gas phase. Solids do not have a boiling point, as they transition directly from a solid to a gas through a process called sublimation.
Boiling Point. Different substances reach this point at different pressures and temperatures.
At room temperature, ice, which is solid water (H₂O), will begin to melt and transition into liquid water as it absorbs heat. The melting point of ice is 0 degrees Celsius (32 degrees Fahrenheit), so when the temperature rises above this point, the solid form converts to liquid. As the temperature continues to increase, the liquid water can eventually reach boiling point and turn into water vapor or steam.
When a liquid is heated, its temperature will increase. As the temperature rises, the molecules in the liquid will gain more energy and move faster. Eventually, if the temperature is high enough, the liquid will reach its boiling point and turn into a gas.
if you were to constantly increase the temperature of a solid you would eventually reach the melting point for that particular substance, at which time the solid would melt to a liquid. if you were to keep heating the substance, at some point the liquid would reach its boiling point and would evaporate to a gas.
No, for a liquid to become a gas it does not necessarily have to reach 100 degrees Celsius. The process by which a liquid changes to a gas is called evaporation and it can occur at temperatures below the boiling point of the liquid.
Each substance has a specific melting point (excepting cases of sublimation or thermal degradation).
The freezing point and melting point of a substance are the same temperature, known as the equilibrium melting point, at which the solid and liquid phases coexist in equilibrium. When a substance is cooling down, it will reach its freezing point temperature, causing it to solidify. Conversely, when a substance is heating up, it will reach its melting point temperature, causing it to liquefy.
The cooling system is pressurized and requires a higher temperature to reach boiling.
No, when a solid is heated and its temperature increases, it is not boiling. Boiling specifically refers to the phase transition of a liquid turning into a gas at its boiling point. As a solid is heated, it will eventually reach its melting point, where it transitions from solid to liquid, and only then, if heated further, can it reach boiling.
