प्रश्न
Argon is an inert gas used in light bulbs to retard the vaporization of the tungsten filament. A certain light bulb containing argon at 1.2 atm and 18°C is heated to 85°C at constant volume. Calculate its final pressure in atm.

उत्तर
P1 = 1.2 atm
T1 = 18°C + 273 = 291 K
T2 = 85°C + 273 = 358 K
P2 = ?
`"P"_1/"T"_1 = "P"_2/"T"_2`
P2 = `("P"_1/"T"_1) xx "T"_2`
= `(1.2 "atm")/(291 "K") xx 358 "K"`
P2 = 1.48 atm
