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.)

Imagine that bubbles begin to form a sample of liquid but the temperature did not change.what must have happened to cause this change?
Decrease in pressure and volume.
What will happen to pressure when gas expands and volume increases?
As the pressure increases, the volume wil decrease.
What property like volume depends of the size of the sample?
The volume and the mass of sample both depend on the size of the sample.A small sample has small volume and small mass, a big sample has big volumeand big mass. But the ratio of mass to volume is constant for a pure sample ofa substance, no matter what size the sample is. That ratio is called the densityof the substance.
As the temperature of a fixed volume of a gas increases the pressure will?
decrease
Why does the density of a substance not change with the sample size?
Density = mass / volume As sample size increases, both mass and volume increase in the same ratio.
When a fixed sample of gas increases in volume?
Decrease its pressure.
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.

Decrease in pressure and volume.
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.
The volume of a sample of water is 20cm3 the mass of?
The volume of a sample of water is 20 cm3. The mass of this sample is closest to
What will happen to pressure when gas expands and volume increases?
As the pressure increases, the volume wil decrease.
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 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.
A sample of zinc is placed in a graduated cylinder. The initial volume of water= 15.0mL and final volume of water and sample= 24.0mL. Determine the mass of the sample of zinc?
what?
What causes density to decrease?
an increase in volume and/or a decrease in mass
Does a decrease in temperature results in a decrease or in crease in the volume of gas?
Temperature is directly proportional to volume i.e. as temperature increases volume of gas also increases and as it decreases, the volume also decreases
