Why has a gas two values of molar heat capacities?
Gasses have two specific heat capacities because the boundary conditions can affect the number by up to 60%. Therefore, a number is given to each boundary condition: isobaric (constant pressure) or isochoric (constant volume). In an ideal gas, they differ by the quantity R (the gas constant - the same one you use in the ideal gas law): Cp = Cv + R where Cp is the isobaric molar heat capacity (specific heat) and Cv is the isochoric molar heat capacity.
Is the molar kinetic energy of chlorine gas equal to greater to or less than the molar kinetic energy of nitrogen at 25 degrees Celsius?
The molar kinetic energy of chlorine gas is equal to the molar kinetic energy of nitrogen gas at 25 degrees Celsius. Temperature is the only factor that determines the average kinetic energy of gas particles, not the type of gas.
Graham's law states that the rate of effusion of a gas is inversely proportional to the square root of the?
molar mass of the gas. This means that lighter gas molecules effuse at a faster rate than heavier gas molecules at the same temperature.
What does a molar volume of a gas at STP occupy?
At STP (standard temperature and pressure), one mole of any gas occupies a volume of 22.4 liters. This is known as the molar volume of a gas at STP.
What are different NAME of constant r?
R may be the Rydberg constant or the gas constant.
What is the mass of 1 mole of gas?
39.95 because that is the molar mass of Argon

What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
What is the molar mass of amonia gas?
The molar mass of ammonia gas (NH3) is approximately 17.03 g/mol.
Is the rate of effusion of a gas directly proportional to any specific factors?
Yes, the rate of effusion of a gas is directly proportional to the square root of its molar mass.
What does molar volume mean for a gas?
Molar gas volume is the volume of ONE moel of gas. It only depends on the pressure and temperature, not on the kind of gas. Molar volume at standard temperature and standard pressure is always 22,4 Litres (for any gas)
Is the molar mass of gas dependant on the type of gas?
Yes, the molar mass of a gas is dependent on the type of gas. Each gas has its own unique molar mass based on the atomic or molecular weight of its constituent elements. This value is used to calculate the amount of the gas present in a given volume using the ideal gas law.
What heats a burner flame?
gas
What is the relationship between the molar mass and the ideal gas law?
The molar mass of a gas is directly related to the ideal gas law, which states that the pressure, volume, and temperature of a gas are related to the number of moles of gas present. The molar mass affects the density of the gas, which in turn influences its behavior according to the ideal gas law.
The molar mass of a certain gas is 49 g. What is the density of the gas in gL at STP?
To find the density of a gas at standard temperature and pressure (STP), we can use the formula: density = molar mass / molar volume. At STP, the molar volume of an ideal gas is approximately 22.4 L. Therefore, the density of the gas with a molar mass of 49 g is calculated as follows: density = 49 g / 22.4 L ≈ 2.19 g/L.
Why is molar volume irrelevant of the size of a gas particle?
Molar volume is based on the volume occupied by one mole of gas molecules at a specific temperature and pressure. It is a macroscopic property and averages out the effect of individual gas particle size because the volume of the container is much larger compared to the size of gas particles. This allows molar volume to be consistent regardless of the size of the gas particles.
Is the molar kinetic energy of chlorine gas equal to greater to or less than the molar kinetic energy of nitrogen at 25 degrees Celsius?
The molar kinetic energy of chlorine gas is equal to the molar kinetic energy of nitrogen gas at 25 degrees Celsius. Temperature is the only factor that determines the average kinetic energy of gas particles, not the type of gas.
