Yes
Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.
Any substance which is liquid at that temperature. Liquids evaporate at any temperature. If you mean boiling, which happens at a fixed temperature at fixed pressure, then nitric acid fits.
The boiling point of water can vary based on factors like altitude and atmospheric pressure. At higher altitudes, where the atmospheric pressure is lower, water boils at a lower temperature. This is because the lower pressure makes it easier for water molecules to escape into the air as vapor.
No, the latent heat of vaporization is not fixed and can vary depending on the substance. It represents the amount of energy required to change a unit mass of a substance from liquid to gas at a constant temperature and pressure.
Pressure will be decreased
A fixed quantity of liquid at a fixed temperature and pressure.

Boiling point at 450°C is a physical property, specifically a characteristic of a substance that describes its behavior in response to changes in temperature. It is a fixed value for a specific substance and indicates the temperature at which the substance changes from liquid to gas at a specific pressure.
By volume liquid can occupy the shape of the container ,but has got a fixed volume unless and until subjected to expansion by change in temperature and pressure. that way it is also compressible. but on the other hand solid has got fixed volume and fixed shape. it is less compressible. this is how they are different..
There is nothing called "condensation point". At least not such thing related to do condensation of gases. But there is a fixed point at a certain pressure, called "boiling point", means, the temperature at which a liquid boils. But condensation does not occur at a fixed temperature like boiling. Think this way, you can see water drops on a cold bottle that occur by condensation of water vapor in the air. For this, just a cold bottle is enough, not a bottle at a certain temperature.
Both mixtures and pure substances have measurable and observable chemical properties and physical properties. A liquid mixture vaporizes over a temperature range; whereas, a pure substance boils at a fixed temperature.
That is true in the sense that when a given quantity of material changes phase (by melting, freezing, boiling, etc.) the amount of mass does not change. Of course, mass may escape. When water boils, the vapor will escape into the air unless you have special equipment to collect it.
It has a fixed mass, volume and density at a fixed temperature. It does not have a fixed shape. It is incompressible.

A liquid (water) takes on the temperature you give it. You need to boil the water if you want to brew a cup of tea. Having brewed your cup of tea, it will take on the shape of the cup you use. Therefore, gas and liquids take on the shape of the container.
