Question

Part Two: Calculations using the Gas Laws. Describe each relationship in one sentence. 1. A container filled with air at a pressure of 1.02 atm has a volume of 2.75 L. If the volume changes to 3.25 L, what is the new pressure? Describe the relationship between pressure & volume. 2. A sample of gas has a volume of 2.8000 L. When submerged in ice water at T = 0.00 °C (273.15 K), its volume decreases to 2.5700 L. What was its initial temperature in Kelvins? Describe the relationship between temperature & volume. 3. A container of gas is initially at 0.500 atm and 25.00 'C. What will the pressure be at 125.00 'C? Describe the relationship between temperature & pressure,

Answer 1

PV, = P2 V₂ + 1.02 X 2.75 = 2 * 3.25 → P₂ = 10°863 atm (answer Al a constant temperature, volume of gas is inversely proportional to its pressure je vas → PV = constant.

뷰 2.8000 2.5700 ' T 273.15 > T, = 1297.59 K At constant pressure, volume of a gas is morensel to its absolute temperature. ie. V&T proportional > y = constant

0.500 B (25.00 +273.15) (125.00 +273.15) → P = 10.668 atm] Camwer) At constant volume, pressure of a gas 'n proportional to ils atesolute temperature. 1.e. P&T → = comtant
