How many times will the gas volume increase at a constant pressure if the temperature is increased

How many times will the gas volume increase at a constant pressure if the temperature is increased from 0 to 280 degrees?

Data: Tg1 – initial abs. temperature of the presented gas (Тг1 = 0 ºС = 273.15 K); Tg2 – increased abs. gas temperature (Тg2 = 280 ºС = 553.15 K).

To find out the increase in the volume of the presented gas, consider the formula (isobaric process): k = Vg2 / Vg1 = Tg2 / Tg1.

Let’s perform the calculation: k = Tg2 / Tg1 = 553.15 / 273.15 ≈ 2 p.

Answer: The volume of supplied gas should be doubled.
