Every substance has their own boiling point.
Temperature and pressure
Properties of a substance, like density or specific heat, aren't affected by changes in temperature and pressure because they are intrinsic characteristics that depend on the nature of the substance itself, regardless of external conditions. These properties are determined by the molecular structure and interactions within the substance, which remain constant despite changes in temperature or pressure.
The phase of a substance is determined by its temperature and pressure, as well as the intermolecular forces present within the substance. Changes in temperature and pressure can cause a substance to transition between solid, liquid, and gas phases.
Changes in temperature, pressure, or the addition of a catalyst can alter the state of an element or compound. Heating can cause a substance to melt or evaporate, while cooling can cause it to solidify or condense. Pressure changes can also affect the state of a substance, for example, raising the pressure can turn a gas into a liquid. Additionally, the presence of a catalyst can facilitate chemical reactions that transform a substance into different states.
A substance's boiling point is the temperature at which it changes from a liquid to a gas.
A thermobarometer in a volumeter is used to measure both temperature and pressure, which are important factors in determining the volume of a substance. By taking into account temperature and pressure, the volumeter can accurately calculate the volume of the substance being measured.
This temperature is called freezing point and is different for each substance or material.
This temperature is called melting point and is different for each substance or material.
The temperature of a flame changes with variables such as the type of substance being burned, pressure etc.
No, the melting point of a substance is the temperature at which it changes from a solid to a liquid, whereas the freezing point is the temperature at which it changes from a liquid to a solid. These points are usually the same for a pure substance under normal atmospheric pressure.
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
