In physics, "boiling" and "freezing" points generally refer to the temperatre and pressure at which liquid water becomes a gas (the "boiling point"), or when liquid water becomes a soild (the "freezing" point).
This can be extended to other compounds as well, although the terms "boiling" and "freezing" are not necessarily used.
More correctly, we should describe phase transition points, the temperature and pressure where any compound undergoes a change from one state of matter (eg, solid --> liquid, or liquid --> gas, or gas --> plasma).
it mean a scale of hot water boiling
There are three states of matter: gas, liquid and solid. The melting point is where a solid turns to liquid. The freezing point is where a liquid turns to solid.
If you mean ammonia, the melting point of ammonia is −77.73 °C, and its boiling point is −33.34 °C. (Wikipedia)
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
That really depends what you mean by grit. If it's just powdered rock, there is no effect. If you mean rock salt, then the freezing point is reduced because the salt dissolves. The lowest freezing point achievable for salt solution is - 21.1 degrees C.
Boiling point is the temperature at which a liquid changes into a gas. Freezing point is the temperature at which a liquid changes into a solid.
Melting (freezing) point: the temperature when the solid metal become a liquid. Boiling point: the temperature when the liquid metal become a gas.
It means boiling points are hot and freezing points are cold.
Freezing point is the temperature required to turn a liquid into a solid. Boiling point is the temperature required to turn a liquid into a gas. Almost everything has a freezing and boiling point. If you mean water well The freezing point is 0oC The boiling point is 100oC If you add a bit salt to the water to make saline then the freezing point is changed and lowered somewhere in the region of -10c (which is why we salt grit our roads in winter)
Melting point & boiling point means the temp that things melt & boil. Water's freezing & melting point is 32 degrees Fahrenheit or 0 degrees Celsius. The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. Different liquids or substances have different melting, freezing, and boiling points.
To scald is to bring a liquid just to the point of boiling.
They're the same thing - it just depends on which direction (of temperature change) you're interested in.
There isn't any but if you mean freezing of 32 degrees and boiling of 212 degrees then it is the Fahrenheit temperature scale.
It means that the temperature setting is in degrees Celsius, based on 0°C as the freezing point of water and 100°C as the boiling point of water.
Boiling is heating any liquid substance over its boiling point, till it changes its state.. Simmering is continuously heating any liquid substance to keep it hot..
Examples are: freezing, liquefaction, sublimation, boiling.
The Celsius temperature scale has 100 degrees between freezing and boiling.
