Unformatted text preview: PV = nRT , where P is pressure, V is volume, n is the number oF moles, R is the gas constant, and T is temperature on the Kelvin scale. In the limit oF vanishing density all ordinary gases are obey the ideal gass law exactly. Say we keep some gas at constant temperature (isothermal) and constant number oF moles (isosomething) and double its volume. The pressure: a) doubles. b) goes to zero. c) increases. d) halves. e) goes to infnity. 020 qmult 00210 2 3 5 moderate math: ideal gas and pressure Extra keywords: physci KB1296 4. The ideal gas law obeyed by all suciently dilute gases is PV = NkT , where P is pressure, V is volume, N is the number oF molecules, k is the Boltzmanns constant, and T is temperature on the Kelvin scale. Say we keep some gas at constant volume. The pressure is then : a) 100 Pa. b) infnite. c) proportional to molecule size. d) zero. e) proportional to temperature....
