The frequency of collisions is reduced
pressure
Yes, a pure liquid will generally boil at a fixed temperature at a given pressure. This temperature is known as the boiling point, and it remains constant as long as the pressure is constant.
Pressure will be decreased
In layman terms, warm air rises and cold air sinks (experience that in a two-story building). Lighter objects float to the top. Therefore, warm air has a lower density than cold air. ===============================
It has a fixed mass, volume and density at a fixed temperature. It does not have a fixed shape. It is incompressible.

A fixed quantity of liquid at a fixed temperature and pressure.
Pressure will be decreased
no, no gas does, it depends on temperature and pressure.
Solids have a fixed volume or shape at room temperature or pressure.
upper fixed point is a temperature of stem from water boiling and standards atmospheric pressure lower fixed point is the temperature of pure melting ice.
You can use the ideal gas law: PV=RTn, where: P is the pressure V is the volume R is the proportionality constant, the so-called "gas constant" T is the absolute temperature n is the number of moles

Yes, liquids have a fixed temperature at a specific pressure until they reach their boiling point, at which point they turn into gas. Liquids do not have a fixed shape and take the shape of their container.
