# How can a change in pressure or temperature will affect the volume of a gas?

123

Pressure is inversely proportional to volume. So when pressure increases, volume decreases. (as per Boyle's law)

Temperature is directly proportional to volume. So when temperature increases, volume increases. (as per Charles's law)

It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density. There are two factors that affect gas pressure. These factors are temperature and volume. Higher volume means lower pressure. Higher temperature means higher pressure.  Its pressure will change in both cases. More temperature = more pressure. More volume = less pressure.  if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure Temperature is not directly tied to volume, its related to pressure. Increasing the temperature will increase the pressure--only if volume is held constant. That is were volume and temperature are related, through pressure. However, if you increase the volume it does not change the temperature.  Increasing the pressure the volume of a gas decrease. Pressure and temperature are directly proportional to each other, temperature increases with the increase of pressure. While pressure and volume are inversely proportional to each other. Volume decreases with the increase of pressure. As the temperature of a gas increases, so does the volume. Change the pressure or change the temperature. Volume changes inversely with pressure and directly with temperature. That is to say, if you squeeze it, it gets smaller. If you heat it, it gets bigger.  P1V1/T1 = P2V2/T2 so with pressure constant V1/T1 = V2/T2 and thus an increase in temperature will result in an increase in volume to balance out. At a constant temperature, the volume and the pressure are inversely proportional, that it, the greater the volume, the lesser the pressure on the gas, and viceversa. If the temperature remains constant, decreasing the volume will increase the pressure. temperature (heat), volume, water vapor, and altitude (how high or low it is) all affect air pressure A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume. To predict how temperature will affect the volume of a gas, pressure must remain constant. Volume in gases decreases with increase in pressure. Generally, heat added to materials causes an increase in volume as well as temperature. If the volume is contained (as with gases), the temperature increases the pressure. As you decrease the volume, the pressure will increase proportionally, and if you increase the volume, then the pressure will decrease.  Pressure can change as a result of: -Change in Temperature -Change in Volume -Change in number of Moles This is based on the formula: PV = nRT where: P is pressure V is volume n is number of Moles R is a constant T is temperature ###### PhysicsScienceChemistryMeteorology and Weather Copyright © 2020 Multiply Media, LLC.
