A gas is at 35.0 ∘c and 2.50 l. what is the temperature at 5.00 l?

To answer this item, it is first assumed that the gas given is ideal such that it follows the equation,

PV = nRT

where P is pressure, V is volume, n is number of moles, R is the universal gas constant, and T is temperature.

If in the equation, only T and V are changed and all else are constant then,

V1/T1 = V2/T2

Substituting the known values,

2.5L / (35 + 273.15) = 5 / (T2)

The value of T2 from the equation is 616.3K which is also equal to 343.15°C.

Answer: 343.15°C
