temperature
Increased pressure causes the gas molecules to come closer together, thus the volume also decreases.
Heating a material causes it to expand, increasing its volume, while cooling a material causes it to contract, decreasing its volume. The expansion and contraction of materials are due to changes in the intermolecular spacing as the temperature changes.
The volume of a sphere is proportional to R3 .So doubling the radius causes the volume to increase by a factor of 23 = 8 .

When pressure is kept constant, a gas causes its volume to decrease when it is cooled. This is described by Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. Therefore, cooling the gas leads to a reduction in its volume.
An increase in temperature causes gas particles to move faster and spread out more, leading to an increase in volume. Conversely, a decrease in temperature causes gas particles to slow down and come closer together, resulting in a decrease in volume. This relationship is described by Charles's Law.
yea,by retention water ,it increase blood volume,which ultimately increase blood pressure..
