Question

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

Answer 1

Answer: 343.15 °C

Step-by-step explanation:

T2/V1 = T2/V2

(35 + 273.15)/2.5 = T2/5

(308.15)/2.5 = T2/5

123.26 = T2/5

(5)123.26 = T2/5(5)

616.3 °K = T2

343.15 °C = T2

Answer 2

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
