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 will happen if the pressure on a sample of gas is raised three times and it's temperature is kept constant?
If the pressure on a sample of gas is raised three times and the temperature is kept constant, according to Boyle's Law, the volume of the gas will decrease proportionally to maintain a constant temperature. This means the gas will be compressed and occupy a smaller volume.
Imagine that bubbles begin to form a sample of liquid but the temperature did not change.what must have happened to cause this change?
The decrease in pressure caused the bubbles to form in the liquid sample without changing the temperature. This could occur, for example, if the liquid was moved to a region of lower pressure, releasing dissolved gases as bubbles.
What will happen to pressure when gas expands and volume increases?
When a gas expands and its volume increases, the pressure of the gas will decrease. This is because pressure and volume are inversely proportional according to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature.
What property like volume depends of the size of the sample?
The property that depends on the size of the sample is extensive. Extensive properties, such as mass and energy, scale with the size of the sample. This means that as the sample size increases, the value of the property also increases proportionally.
A sample of xenon gas occupying 10.0ml is collected in laboratory at 27 C and 1.25atmosphere.what is the volume at standard condiions?
To calculate the volume at standard conditions, we can use the ideal gas law equation, PV = nRT. First, calculate the number of moles of xenon gas using the given conditions. Then, using the molar volume at STP (22.4 L/mol), calculate the volume of xenon gas at standard conditions.
Why volume of toluene decrease after extraction?
It may trapped in your sample, if it's a polymer for example. Or it may reacted with a substance in the solution.
When a fixed sample of gas increases in volume?
When a fixed sample of gas increases in volume, its pressure decreases because the gas particles have more space to move around, resulting in fewer collisions with the container walls. The temperature of the gas typically remains constant.
How did the effect of freezing the sample differ from the effect of boiling?
Freezing the sample causes the molecules to slow down and come closer together, often leading to a decrease in volume and possibly forming a solid. Boiling the sample provides energy to the molecules, causing them to separate from each other and enter a gaseous state, thereby increasing the volume.
What are the Kinetic Molecular Theory effects on the pressure and volume of the gas sample?
According to the Kinetic Molecular Theory, pressure is the result of gas molecules colliding with the walls of the container. As the volume of the gas sample decreases, the frequency of collisions increases, leading to an increase in pressure. Conversely, as the volume increases, the frequency of collisions decreases, leading to a decrease in pressure.
What is a result to increasing the temperature of a gas?
In a closed system the pressure increase. In other conditions the volume increase and the density decrease.
Would stroke volume increase or decrease if your unhealthy?
Stroke volume can decrease if you are unhealthy. Health conditions such as heart failure, heart disease, or dehydration can negatively affect the heart's ability to pump blood effectively, leading to a decrease in stroke volume.
What will happen if the pressure on a sample of gas is raised three times and it's temperature is kept constant?
If the pressure on a sample of gas is raised three times and the temperature is kept constant, according to Boyle's Law, the volume of the gas will decrease proportionally to maintain a constant temperature. This means the gas will be compressed and occupy a smaller volume.
Why must a metal sample always be dry before its mass or volume is taken?
A wet metal sample can have water molecules attached to its surface, which can affect its mass and volume measurements. Removing water ensures accurate data and prevents errors in calculations.
Imagine that bubbles begin to form a sample of liquid but the temperature did not change.what must have happened to cause this change?
The decrease in pressure caused the bubbles to form in the liquid sample without changing the temperature. This could occur, for example, if the liquid was moved to a region of lower pressure, releasing dissolved gases as bubbles.
How does temperature affect the volume of substance?
An increase in temperature will cause an increase in volume, while a decrease in temperature will cause a decrease in volume.
What will happen to the density if you keep the volume the same and you decrease the mass?
If you decrease the mass while keeping the volume constant, the density of the object will decrease. Density is calculated by dividing mass by volume, so a decrease in mass with a constant volume will result in a lower density.
What is a one in two dilution?
It means you dilute your sample in a volume that is as great as the one you current sample has. Ex: you dilute 50 ml NaCl-solution in 50 ml MQ-water. The result of this is that the concentration will always be halved, seeing as the volume increases twofold.
