Three variables that effect volume (V) of gas are pressure (P), temperature (T), and how many moles (n) of gas are present in a system. Decreasing any of these variables correspond to gas volume reductions. These can be related by the Ideal Gas Law equation of PV = nRT. R is the Ideal Gas constant of .0821 Liters/ATM*moles*Kelvin.

How in terms of collision theory how a decrease in concentration can change the rate of a precipitation reaction?
Decrease in conc. means decrease in no. of molecules per unit volume. Since, molecules or atoms will less in number, the no. of colliding particles will be less. This will lead to decreased precipitation
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 effect does the obsence of heat have on air molecules?
The absence of heat causes air molecules to lose energy and slow down, leading to a decrease in their kinetic energy and movement. This can result in a decrease in air pressure, density, and volume. Ultimately, the absence of heat can lead to a decrease in temperature and the formation of colder air masses.
What happens to the mean free path of the molecules in this process if a helium filled balloon initially at room temperature is placed in a freezer will its volume increase decrease or remain the same?
The volume decrease.
Do liquid have more molecules when cold or when warm?
Liquids generally contain more molecules when they are warm than when they are cold. As temperature increases, the molecules gain energy and move apart, allowing more molecules to occupy a given volume. Conversely, when liquids cool, the molecules lose energy and come closer together, resulting in a decrease in the number of molecules that can fit in that same volume. However, the total number of molecules in a fixed amount of substance remains constant regardless of temperature.
Can the removing of energy increase the volume of a substance because the molecules come closer together?
No. It can increase the volume in some cases, but not BECAUSE the molecules come closer together. If the molecules come closer together, the volume will DECREASE.
How bronchial asthma effect on lung volume and capacity increase or decrease and why?
decrease -
What will cause a decrease in a gas pressure in a closed container?
A decrease in temperature or a decrease in the number of gas molecules in the container will cause a decrease in gas pressure. Alternatively, if some of the gas molecules escape from the container, the pressure will also decrease.

Why does the volume of a gas decrease when pressure increases?
As pressure increases, the molecules of the gas are compressed, reducing the amount of space between molecules, which results in a decreased volume.
What is the effect of a decrease in volume of a sealed container of gas with no change in temperature?
A decrease in volume of a sealed container of gas with no change in temperature leads to an increase in pressure according to Boyle's Law. This is because the gas molecules are confined to a smaller space, resulting in more frequent collisions with the container walls.
How does the volume of an ideal gas at constant temperature and pressure change as the number of molecules increases?
The volume of an ideal gas will increase as the number of molecules increases at constant temperature and pressure. This relationship is described by Avogadro's law, which states that the volume of a gas is directly proportional to the number of molecules present, assuming constant temperature and pressure.
What causes decrease of density in warming water?
As water warms, the thermal expansion effect causes the water molecules to spread out, leading to a decrease in density. This is because warmer water is less dense than colder water. The increase in temperature causes the water molecules to move faster and spread out, resulting in a decrease in the mass of water within a given volume.
What happens to the mean free path of the molecules in this process if a helium filled balloon initially at room temperature is placed in a freezer will its volume increase decrease or remain the same?
The volume decrease.
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
