If the space in which the gas is inside doesn't change, the volume of gas doesn't change
When the number of gas particles at constant pressure increases, the volume of the gas will increase due to the additional collisions between the gas particles and the walls of the container. This causes the gas to take up more space to accommodate the increased number of particles.
The volume stays the same if it is in a container. If it is not then the volume will increase.PV = nRTPressure times Volume = number of moles times Gas constant times temperatureThus if you raise temperature, pressure and/or volume must increase.
When air pressure increases, the density of the air also increases. This is because the air molecules are being compressed closer together, resulting in a higher concentration of air particles within a given volume. The relationship between air pressure and density is described by the ideal gas law, which states that pressure is directly proportional to density when temperature and volume are held constant.
Assuming that pressure and the amount of matter are constant (meaning they do not change), volume will increase as temperature increases.
Directly proportionalWell the reason is:as you usually know, when you increase volume, pressure should decrease.but in a case of constant pressure, as volume increases, well, pressure stays the same.So how does that work? The only reason pressure wouldn't change is if the temperature will increase, allowing molecules of gas to move more rapidly, and therefore creating pressure that stays constant, as the volume increases. (but if you would keep increasing temperature under constant volume, pressure would actually increase).
The volume will increase in proportion to the increase in absolute temperature.
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.
Arteries are high-pressure vessels. However, this pressure is not constant. As the heart pumps blood into the arteries, the pressure dramatically increases. They must stretch to accommodate this change, or risk rupturing.
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
since PV=nRT and we assume that the number of moles and temperature remains constant, we can assume that PV=R as R the gas constant will not change, if pressure is increased, then volume must decrease to counteract the change in pressure
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
In Boyle's law, pressure and volume are the two variables that change. The relationship between pressure and volume is inverse; as pressure increases, volume decreases, and vice versa, when the temperature is kept constant.
