Molar specific heats of a gas refer to the amount of heat required to raise the temperature of one mole of the gas by one degree Celsius (or Kelvin) at constant pressure or constant volume. The specific heat capacity at constant pressure is denoted as Cp, and at constant volume as Cv. These values are important in understanding the thermodynamic behavior of gases.

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 happens to the pressure of the gas in the container?
The pressure increases if the container gets smaller or the gas heats up. The pressure decreases if the container gets bigger or the gas cools off.
What does a molar volume of a gas at STP occupy?
22.4 liters.

Is the molar mass of gas dependant on the type of gas?
Yes as is the molar mass of anything else.
Molar volume of liquid is greater than molar volume of gas. why?
That's not true. The molar volume of a gas is always greater than the molar volume of a liquid. I can't think of any exceptions to this.
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)
What is the molar mass of amonia gas?
Molar mass of NH3 = 17.03052g/mol
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
The molar concentration of a gas at standard temperature and pressure (STP) does not depend on the identity of the gas because at STP, all gases occupy the same volume per mole, which is 22.4 liters. This is based on Avogadro's law, which states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
What heats a burner flame?
gas
How does molar mass effect pressure at a constant temp and volume?
Molar mass does not directly affect pressure at a constant temperature and volume. Pressure is determined by the number of gas molecules present and their average kinetic energy. However, at constant temperature and volume, gases with higher molar masses will have lower average speeds and therefore exert lower pressures compared to gases with lower molar masses.
Occurs when a gas heats up?
expansion
What is Oxygen (O2) is an example of?
The molar mass of any gas in liters is 22.4 For example The molar mass of O2 and O are both 22.4 since gas is compressible.
Molar Mass Of Magnesium from gas law stoichiometry where would this apply?
The molar mass of magnesium can be determined using gas law stoichiometry when the mass of magnesium reacted and the volume of gas produced are known. By measuring the volume of gas produced during the reaction of magnesium with an acid, and knowing the pressure, temperature, and number of moles of gas, the molar mass of magnesium can be calculated using the ideal gas law equation PV = nRT and stoichiometry relationships.
What is molar and molal volume?
Molar volume is the volume occupied by one mole of a substance at a specific temperature and pressure, typically measured in liters per mole. Molal volume is the volume of solvent used to dissolve one mole of solute and is typically expressed in liters per mole. Both are important concepts in chemistry for determining the properties of substances and solutions.
