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?
equal to
What heats the water?
Water gets heated in different ways in different places. Outdoors, sunlight heats water. In a house, water heaters usually run on natural gas. On a stove, it could be either gas or an electric coil.
Explain the construction of an air conditioner?
it compresses a gas (freon or something like it), which heats the gas. Then it cools the gas (radiator grill on the outside) Then it lets the gas expand ... which cools the gas ... which cools the inside air.
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.

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?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
What heats a burner flame?
gas
How does molar mass effect pressure at a constant temp and volume?
Assuming we are dealing with a gas, the ideal gas equation can be used.P*V = n*R*Twe can solve for n asn = (P*V)/(R*T)R can be defined for a specific gas to give the specific gas constant. In which case, we notate as "R-bar".R-bar = R/atomic massIf the solution under consideration is a liquid or a solid, the ideal gas equation is not valid. Given the volume of the liquid or solid, we can calculate the mass from the density sincedensity = mass/volumeThen we can find the number of moles of the substance by dividing the mass by the molar mass (check your units on this step).mass/molar mass = number of moles
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?
Both the molar mass of magnesium (24.3g/mol) and the gas laws come into play in stoichiometry.
What is molar and molal volume?
The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.
