The molar volume of a liquid is greater than that of a gas because in a liquid, the particles are closer together and have stronger intermolecular forces holding them in place, resulting in a higher density compared to a gas where particles are more spread out and have weak intermolecular forces. This leads to a smaller volume per mole for gases compared to liquids.
Molar heat of fusion: the heat (enthalpy, energy) needed to transform a solid in liquid (expressed in kJ/mol). Molar heat of vaporization: the heat (enthalpy, energy) needed to transform a liquid in gas (expressed in kJ/mol).
If gas bubbles escape the volumetric flask, the calculated molar mass of the gas will be less than the theoretical molecular value. This is because the number of moles of gas remaining in the flask will be underestimated, leading to a lower molar mass calculation.
As a liquid or gas? And if a gas, at what pressure? At sea level (1 atmosphere), 22.4 L of any given gas contains exactly one mole of the gas.
Of course less denser, because a gas is always less denser than liquid.

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.
Gas is much less dense than liquid.

In the van der Waals equation, the excluded volume is considered to be less than the molar volume because it accounts for the volume occupied by gas molecules themselves, which reduces the available space for the gas particles to move around freely. This reduced effective volume results in a difference between the molar volume and the true volume of the gas.
helium is a gas less dense than air.
Yes, flux core welding does not require the use of gas because the flux core wire itself produces a shielding gas to protect the weld from contamination.
You could calculate the molar heat of sublimation as long as you know by placing a known amount of a known quantity in a calorimeter and measuring the change in temperature during sublimation. Then use the equation E=mc(change in T) where E is energy in joules, m is mass, c is heat capacity, and T is temperature.
you dont .thats what the flux does.solid core wire needs gas
