Question

Charles’s law states that for a given mass of
gas at constant pressure the volume is directly
proportional to its thermodynamic temperature. A gas occupies a volume of 2.25 litres at
300 K. Determine (a) the constant of proportionality, (b) the volume at 420 K, and (c) the
temperature when the volume is 2.625 litres.

Answer 1

volume is directly proportional to temperature, meaning V = kT

for part a), plug in V = 2.25L and T = 300K, solve for k
b) T = 420K, k = the value calculated in part a), plug in and solve for K
c) similar logic, but plug in V = 2.625L and solve for T
