Why can boiling points and freezing points be used to identify substance?
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
What do terms ''boiling point'' and '' freezing point '' mean?
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.
What do the terms ''boiling point'' and freezing point mean?
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).
Why is it better to say the boiling point and freezing point of pure water?
It's more accurate to specify "boiling point" and "freezing point" to avoid confusion, as the definition of the terms can vary. For water, the boiling point is 100 degrees Celsius and the freezing point is 0 degrees Celsius at standard atmospheric pressure.

What temperature control is better Celsius or Fahrenheit?
Both Celsius and Fahrenheit are suitable for temperature control, but Celsius is more commonly used in scientific applications and in most countries worldwide. Celsius is easier to understand in terms of the freezing and boiling points of water, with 0°C marking the freezing point and 100°C marking the boiling point.
Can you account for the boiling point of your product in terms of the known boiling points of the pure components of your mixture?
The boiling point of a mixture is typically between the boiling points of its individual components due to the vapor pressure lowering effect of mixing. This can be estimated using methods like Raoult's law or boiling point elevation formula. The actual boiling point of the mixture would depend on the specific concentrations of the components in the mixture.
How the two terms freezing point and melting point relate to one another?
These terms are synonyms.
When are the terms melting point and freezing point used?
The term "melting point" is used to describe the temperature at which a substance changes from a solid to a liquid. The term "freezing point" is used to describe the temperature at which a substance changes from a liquid to a solid.
Why in chemical terms is anti-freeze added to car windscreen wash?
Antifreeze is added to car windscreen wash to lower the freezing point of the liquid. This prevents the solution from freezing in cold temperatures, which can damage the system and obstruct vision during driving. Antifreeze typically contains chemicals like ethylene glycol or propylene glycol that are effective in preventing freezing.

What do the terms boiling points and freezing points mean?
The boiling point of an object is the point at which the substance's atoms/molecules because too "excited" and begin to break free from their current liquid state. Heat is a type of energy. Heating an object makes the object's atoms move quicker and quicker, until they eventually break that bond that they have with each other and move on into the next energetic state. A solid is a low-energy state, a liquid is a moderate-energy state, and as you guessed, a gas is a high-energy state. All this energy talk is the energy in the atoms, to clarify. The faster the atoms move, the higher the temperature, the closer it is to moving on to the next energetic state. The freezing point of an object is just the opposite, it is the point where enough energy is lost within the atoms/molecules of the substance to move down to the less-energetic state, a solid.
