The density of a fixed gas is influenced by temperature and pressure according to the ideal gas law (PV = nRT). As temperature increases, the kinetic energy of gas molecules rises, causing them to spread apart and resulting in a decrease in density. Conversely, increasing pressure compresses the gas molecules closer together, thus increasing density. Therefore, density is directly proportional to pressure and inversely proportional to temperature for a fixed amount of gas.
What else can I help you with?
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
If you want to predict how temperature will affect the volume of a gas what other factor must be held constant?
pressure
Does pure liquid boils at fixed temperature at a given 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.
What As a temperature of a fixed volume of a gas increases the pressure will?
Pressure will be decreased
Which gas law has the assumptions of a fixed amount and temperature of a gas?
The gas law that assumes a fixed amount and temperature of a gas is Boyle's Law. This law states that the pressure of a gas is inversely proportional to its volume when the temperature and the amount of gas remain constant. In mathematical terms, it can be expressed as ( P_1V_1 = P_2V_2 ). This relationship highlights how changes in volume affect pressure under constant conditions.
What are the characterstics of liquid?
It has a fixed mass, volume and density at a fixed temperature. It does not have a fixed shape. It is incompressible.

Does pure liquid boils at fixed temperature at a given 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.
It has a definite volume but has no definite shape what is the answer?
A fixed quantity of liquid at a fixed temperature and pressure.
What As a temperature of a fixed volume of a gas increases the pressure will?
Pressure will be decreased
Do solids have no fixed volume or shape?
Solids have a fixed volume or shape at room temperature or pressure.
Does oxygen has fixed volume?
no, no gas does, it depends on temperature and pressure.

What is the relationship between volume temperature and pressure that is useful for designing things with fixed-volume pistons?
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
What is lower fixed point?
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.
Does air pressure decrease as density decrease?
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. ===============================
