Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.
The point at which a liquid becomes a gas is the boiling point. The point at which a gas becomes a liquid is still called the boiling point. A solid going straight to gas without passing through a liquid state is called sublimation. Dry Ice solid CO2 is a substance that that sublimes.
Liquid changes to gas when pressure is reduced and temperature is increased. When pressure on liquid is reduced, the inter molecular space increases and temperature increases the kinetic energy of the atoms. This changes liquid to gaseous state
it is a gas but when it condenses it becomes a liquid
Generally a solid. Although one also needs to take pressure in consideration to be exact.
No. Going from solid to liquid at constant temperature is an endothermic process. The required amount of energy is called "heat of fusion" of the material that changes state.
The physical property that describes the temperature at which a solid becomes a liquid is called the melting point. It is the temperature at which the solid and liquid phases of a substance coexist in equilibrium.
The process by which a solid becomes a liquid is called melting. This transition occurs when the solid's temperature increases above its melting point, causing the solid's crystalline structure to break down and transform into a liquid state.
The temperature at which a crystalline solid becomes a liquid is called the melting point. It is the specific temperature at which the solid transitions into a liquid state, with the intermolecular forces holding the solid lattice structure being overcome.
A solid becomes a liquid when it temperature has reached its Melting Point (also called it Point of Fusion.)
The process by which a liquid becomes a solid is called "freezing".
No, mercury does not become solid in hot temperature and liquid in coolest temperature. But mercury becomes gas or liquid in hot temperature and becomes solid in coolest temperature. Mercury becomes solid after freezing point of -38.72 degrees Celsius. Solid Mercury can become superconductor in reaching of its critical temperature 4.2 K. Mercury is liquid under the room temperature (25 degrees Celsius). Mercury becomes gas after boiling point of 357 degrees Celsius.
the temperture and pressure at witch a soild becomes a liquid
When solid ice becomes liquid, the temperature goes higher.
It is different for different substances. the generic name for the temperature at which a solid becomes a liquid is the melting point. For a pure chemical compound or an element this is usually a sharp temperature rather than a range.
This phenomenon is called melting, the ordered molecules of the solid becomes non-ordered in the liquid phase.
This is known as deposition which is the opposite of sublimation.
The point at which a liquid becomes a gas is the boiling point. The point at which a gas becomes a liquid is still called the boiling point. A solid going straight to gas without passing through a liquid state is called sublimation. Dry Ice solid CO2 is a substance that that sublimes.
