Under which conditions will the volume of a given sample of a gas always decrease?
The Ideal Gas Law states that PV=nRT, where P=pressure, V=volume, n=number of moles of gas, R=the relativity constant, and T=temp in Kelvin. According to this law, volume (V) varies as V=(nRT)/P. Using this, we can determine that the volume would normally increase with an increase in the number of moles and/or an increase in the temperature and/or a decrease in pressure. Therefore, we can logically determine that the volume of a gas would decrease in the instance of increasing temperature if either the number of moles of gas was decreased or the pressure was increased (to an extent where the level of volume increase by temperature change has been overcome.)
What happens to the partial pressure of oxygen in the air if the air temp increases?
When the air temperature increases, the partial pressure of oxygen remains the same in the air. This is because the partial pressure of a gas in a mixture is determined by its concentration and is independent of the temperature, assuming the volume and moles of other gases remain constant.
Which graph shows the pressure temperature relationship expected for an ideal gas?
The ideal gas law states that pressure is directly proportional to temperature when volume and quantity of gas are constant. Therefore, a graph showing pressure on the y-axis and temperature on the x-axis with a linear relationship would represent the pressure-temperature relationship for an ideal gas.
How does Jacques Charles law relate to aerodynamics?
He 'flew' in helium balloons. Volume increases as temperature increases. In a hot air balloon temp increases so volume increases and some air must leave the balloon. The balloon now has lift because it weighs less than the cold air outside the balloon, just like buoyancy of a boat in water.
What is the technical reason for deterioration in performance of a gas turbine when the ambient temperature rises?
As the surrounding/ambient temperature increases, the temp of air entering the air compressor increases which means that the it's specific volume of air increases. Since the work of compressor = delta pressure x specific volume of air, then as the specific volume of air increases the work input of compressor increases and this is a problem because the total out put power of the turbine = work of the turbine - work of the compressor, so as the work of compressor increases, the total out put work of the gas turbine decreases. And that's why the efficiency of gas turbine is better in winter than in summer.
What is boyals law how does it relate to gases?
Boyle's law states that the pressure of a gas is inversely proportional to its volume, given a constant temperature. This means that as the volume of a gas decreases, its pressure increases, and vice versa. Boyle's law is one of the fundamental gas laws that describes the behavior of gases under changing conditions.
What is the name of the scientific law air pressure and volume?
The scientific law that relates air pressure and volume is Boyle's law. It states that at a constant temperature, the pressure exerted by a gas is inversely proportional to its volume. In other words, as the volume of a gas decreases, its pressure increases, and vice versa.
What is pressure an temp relationship?
The pressure and temperature relationship is described by the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature when volume and amount of gas are kept constant. This relationship can be expressed as P ∝ T, meaning that as temperature increases, pressure also increases proportionally.
What is the relation ship between temp and volume of gas?
The increase of the volume of a gas is direct proportional upon the increase of the temperature. This is the Charles law: V1T2=V2T1
When a pressure on a gas increases will the volume increase or decrease?
For a fixed mass of gas, the gas will become compressed by pressure and its volume will decrease. This is why pressurized gas containers explode when breached: the container breach eliminates the barrier between the gas compressed by the container and the outside air; the pressurized gas immediately increases the volume it occupies in the explosive decompression until its density equals the density of the regular atmosphere.
Do objects with a high density have a small volume for their mass?
No, Density is directly proportional to mass; Density increases as the mass increases, density decreases when mass decreases. Density is inversely proportional to volume; Density decreases when volume increases, density increases when volume decreases.
What is the relationship between the kelvin temperature and the pressure of gas?
Increased temperature = increased volume of gas The above answer is non-sense. The pressure could increase with temperature and actually yield a smaller volume... here ya go: The ideal gas law is: PV = nRT, where P = pressure, V = volume, n= number of moles, R = ideal gas constant, T = Temperature in K
Does water get heavier or lighter as the land temperature increases?
If you consider an amount of watermolecules, they weigh at all times the same. If you consider a volume of watermolecules, as temp increases, molecules expand, and there will be less molecules for the same volume, thus reducing weight per volume.
What is the effect of temperature on volume?
As temperature increases, the volume of a substance typically increases due to the particles moving more rapidly and spreading out. This relationship is described by the ideal gas law equation, which shows that temperature and volume are directly proportional for ideal gases.
If the planet is close to the sun then the more the temp increases is your hypothesis right?
if the planet is close to the sun then the temp increases
What happens to volume if pressure remains the same and temperature goes up?
If pressure remains the same and temperature increases, the volume of a gas will also increase. This is because the particles in the gas gain energy and move more rapidly, causing them to push outwards on the walls of the container, resulting in an increase in volume.
What would happen if the volume of gas decreased and then increased?
The temp of the gas would first rise, then drop. If the final volume of the gas is lower than the volume at the start, the temp will be higher than at the start. If the final volume is greater than at the start, then the temp of the gas will be lower than at the start.
