Answer:
277.16 K is the temperature of the gas.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas =
V = Volume of gas =
n = number of moles of gas =
R = Gas constant = 8.314 J/mol.K
T = Temperature of gas = ?
Putting values in above equation, we get:
T = 277.16 K
277.16 K is the temperature of the gas.
Answer:
density increases with more helium because of its molar mass
<span>Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton also stated that all compounds were composed of combinations of these atoms in defined ratios. He postulated that chemical reactions resulted in the rearrangement of the reacting atom.

Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel) does not contribute carbon dioxide (CO2) emissions to the atmosphere, unlike fossil fuels (coal, oil and natural gas).
