A syringe initially holds a sample of gas with a volume of 285 mL at 355 K and 1.88 atm.To what temperature must the gas in the syringe be heated/cooled in order to have a volume of 435 mL at 2.50 atm?
A) 139 K
B) 572 K
C) 175 K
D) 466 K
E) 721 K

Using the combined gas law: (P1 * V1) / T1 = (P2 * V2) / T2, solve for T2: T2 = (P2 * V2 * T1) / (P1 * V1). Substituting the given values: T2 = (2.50 atm * 435 mL * 355 K) / (1.88 atm * 285 mL) = 721 K.
