W=P(Vf-Vi)
W=(2x10^5pa)*(6.00m^3 - 3.00m^3)
W=6x10^5 pam^3
But 1 pascal is equal to 1 (Newton)/(meter^2)
W=6x10^5 Nm=6x10^5 Joules
"Constant pressure" means the pressure must not change.
In a closed system with constant pressure and no input or output of heat, the gas temperature will remain constant. In that same system, if the pressure is increased, then the gas temperature will also increase. If pressure is decreased, then the gas temperature will decrease.
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
The temperature and pressure.
This is explained by Charle's law. Keeping volume constant, as the temperature increases then the pressure of the gas also increases.
Temperature increases as pressure increases.
As pressure increases, if temperature is constant, the gas will decrease in volume.
The product of pressure and volume. Does PV = nRT look familiar? (:
At constant temperature p.V=constant, so pressure INcreases when decreasing the volume.
As pressure increases, if temperature is constant, the gas will decrease in volume.
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.
"Constant pressure" means the pressure must not change.
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
In physics and chemistry, monatomic is a combination of the words "mono" and "atomic," and means "single atom." It is usually applied to gases: a monatomic gas is one in which atoms are not bound to each other. At standard temperature and pressure (STP), all of the noble gases are monatomic. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form compounds, but the lighter ones are unreactive. All elements will be monatomic in the gas phase at sufficiently high temperatures. The only mode of motion of a monatomic gas is translation (electronic excitation is not important at room temperature). Thus in an adiabatic process, monatomic gases have an idealised γ-factor (Cp/Cv) of 5/3, as opposed to 7/5 for ideal diatomic gases where rotation (but not vibration at room temperature) also contributes. Also, for ideal monatomic gases: : the molar heat capacity at constant pressure (Cp) is 2.5 R = 20.8 J K-1 mol-1 (4.97 cal K-1 mol-1); : the molar heat capacity at constant volume (Cv) is 1.5 R= 12.5 J K-1 mol-1 (2.98 cal K-1 mol-1); where R is the gas constant.
as the pressure decreases the volume of gas increases at constant temperature
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
Increasing the temperature of a gas will increase it's pressure ONLY if the volume is held constant.
