Question
Calculate the following:
The temperature to which a gas ‘P’ has to be heated to triple it’s volume, if the gas originally occupied 150 cm3 at 330K [pressure remaining constant].
Solution
T1 = 330 K
V1 = 150 cm3
Final conditions
T2 = ?
V2 = 3 × 150 = 450 cm3
At constant pressure `"V"_1/"T"_1 = "V"_2/"T"_2`
∴ T2 = `("T"_1"V"_2)/"V"_1 = (330 xx 450)/150` = 990 K
⇒ T2 = 990 - 273 = 717°C
