The pressure P, the volume V, and the temperature T (in Kelvin) of a confined gas are related by the ideal gas law P V = kT , where k is a constant. If P = 0.5 pascal when V = 50 cm³ and T = 360 K, determine by approximately what percentage P changes if V and T change to52 cm³ and 351 K, respectively. A) 6.5 % B) 1.5 % C) -4.5 % D) -6.5 % E) -1.5 %

Using the ideal gas law, calculate the initial and final pressures. The initial pressure is 0.5 pascal. The final pressure is approximately 0.467 pascal. The percentage change is ((0.467 - 0.5) / 0.5) * 100% ≈ -6.5%.
