What is constant pressure gas thermometer?
the thermometer that works on constant pressure
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
If you want to predict how temperature will affect the volume of a gas what other factor must be held constant?
pressure
When the volume and number of particles of a gas are constant is also constant?
The temperature and pressure.
What Air pressure exerted equally on an object from different directions is what type of pressure?
constant pressure
How does the volume and pressure change in a tire after a long drive?
The volume is constant. The pressure will increase.The volume is constant. The pressure will increase.
What is constant pressure gas thermometer?
the thermometer that works on constant pressure
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
Why Do Gasses Have Two Specific Heats?
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.
When temperature and number of particles of a gas are constant what is also constant?
The product of pressure and volume. Does PV = nRT look familiar? (:
When the temperature is constant will the the volume of a gas decrease as the pressure decreases?
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
When does raising the temperature of gas increase its pressure?
Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
When the temperature of of gas increases at constant pressure its?
As pressure increases, if temperature is constant, the gas will decrease in volume.
According to Charles's law for a fixed quantity of gas at constant pressure which of the given quantities is constant?
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
How did pressure effects the sound when temperature 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.
Is sulfur trioxide a compound or element or heterogeneous or homogeneous?
Sulfur trioxide is a compound, and at standard temperature and pressure is a gas and therefore is homogeneous.
What is heat of enthalphy?
Enthalpy H is a thermodynamic state function, that is defined for homogeneous systems as H = U + P V where U is the internal energy of the system, P the pressure and V the volume. If we perform a transformation of the system between the states 0 and 1 maintaining the pressure constant, for the first thermodynamic principle, we have U1 - U0 = Q - P (V1 - V0) where Q is the heat the system absorbs during the transformation. From the definition of enthalpy we also have H1 - H0 = U1 - U0 + P (V1 - V0) Putting together the last two equations we get that, if pressure is maintained constant, H1 - H0 = Q that is the variation of enthalpy is equal too the heat absorbed during the transformation. Naturally this is not true if the pressure is not constant, but the case of constant pressure is particularly important since almost all chemical equations happen at constant pressure.
