When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
What As a temperature of a fixed volume of a gas increases the pressure will?
Pressure will be decreased
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
Does pure liquid boils at fixed temperature at a given pressure?
Yes
What four things affect pressure?
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
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.
When a fixed sample of gas increases in volume what happens to the pressure and temperature?
The frequency of collisions is reduced
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
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
Does oxygen has fixed volume?
no, no gas does, it depends on temperature and pressure.
Do solids have no fixed volume or shape?
Solids have a fixed volume or shape at room temperature or pressure.
Does pure liquid boils at fixed temperature at a given pressure?
Yes
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.
What is the formula for finding pressure?
I suppose you mean the formula for the variation in pressure. The simplest expression of this is, at a fixed temperature,and for a given mass of gas, pressure x volume = constant. This is known as Boyle's Law. If the temperature is changing, then we get two relations: 1. If the pressure is fixed, volume = constant x temperature (absolute) 2. If the volume is fixed, pressure = constant x temperature (absolute) These can be combined into the ideal gas equation Pressure x Volume = constant x Temperature (absolute), or PV = RT where R = the molar gas constant. (Absolute temperature means degrees kelvin, where zero is -273 celsius)
How do you define Charles's law?
At fixed pressure, the temperature is directly proportional to the volume
If the temperature is high is the pressure high?
The original answer stated "No, if the temperature is high the pressure is low. And visa-versa." This is flat wrong. The pressure-temperature law states that the pressure of a gas of fixed mass and fixed volume is directly proportional to the gasses absolute temperature. This can be stated as P/T=k where: P = pressure T = Temperature k = a constant. High Temperature Protection Sleeve - Protects hydraulic hoses, cables and wires. Yancheng Hengsheng Insulation Co.,Ltd
