An open flask contains air at 27^(@)C . Calculate the fraction of air that would be expelled out, at 477^(@)C .

An open vessel contains air at 29^(@)C . To what temperature it must be heated to expel one-third of the air?

An open steel vessel has an ideal gas at 27^@C . What fraction of the gas is escaped if the vessel and its contents are heated to 127^@C ? (neglect the expansion of steel)

An open vessel contains air at 27^(@)C . At what temperature should the vessel be heated so that 1/4h of air escapes from the vessel? Assume that volume of the vessel remains same on heating.

An open vessel has a temperature of TK. When the vessel is heated at 477^(@)C , three fifths of air in the vessel escapes out. What fraction of air in the vessel would have been expelled out if the vessel were heated at 900 K (assume that volume of the vessel remains unchanged on heating)-

An open flask contains air at 27°C.To what temperature it must be heated to expel one-fourth of the air?

An open vessel contains air at 27^@C . To what temperature should the vessel be heated so that the number of molecules in the vessel decreases by 25% ? (Neglect the expansion of the container).
