Question

A gas is enclosed in a room. The temperature, pressure, density and number of respectively are t°C, p atm, ρ g cm-3 and n . What will be the values of pressure, temperature, density and the number of ***** if an equal volume of the gas at pressure p and temperature t is let inside the same room?

Answer 1

When the same volume of another gas is introduced in the same room, i.e., the volume *** constant, then

No. of = n + n = 2n (equal volume contains equal no. of )

Total pressure = (p + p) atm = 2p atm (increases due to addition of another gas)

Temperature = t°C (unchanged)

Density = 2 ρ g cm-3 (gets doubled)
