Want this question answered?
the thermometer that works on constant pressure
"Constant pressure" means the pressure must not change.
pressure
The temperature and pressure.
constant pressure
Good luck!
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.

One is for constant pressure, the other is for constant volume. These are not the same; for example, if the pressure is maintained constant, and the gas is heated, the volume changes.
The product of pressure and volume. Does PV = nRT look familiar? (:
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
As pressure increases, if temperature is constant, the gas will decrease in volume.
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
As pressure increases, if temperature is constant, the gas will decrease in volume.
