A4 L sample of gas is heated from 20 K to 200 K. What will its final volume be?
A.40 L
B.0.4 L
C.200L
D.180 L
E.20L

A. 40 L

Explanation:

Volume and temperature are directly related; when one increases, the other also increases. This can be seen as in the equation V₁ / T₁ = V₂ / T₂. To find the final volume, rearrange the equation to V₂ = V₁ x T₂ / T₁ and plug in your values, then solve.

what's the question?

explanation:

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm
