At a temperature of 70C, the air pressure in the cylinder is 3 * 104 Pa. At what temperature will the pressure in it be 6 * 104Pa?

According to Charles’s law at constant volume (V = const):
P1 / T1 = P2 / T2
T2 = T1 * P2 / P1 = 70C * (6 * 104Pa) / (3 * 104Pa) = 140C
140C let’s translate into Kelvin:
273 + 140 = 413K
Answer: 413K
