The graph A is drawn at high temperature and low pressure and graph B is drawn at low temperature and high pressure.(a) Which graph represents ideal behaviour?(b) Give the equation for combined gas law. (c) A balloon occupies volume of 700 mL at 25°C and 760 mm of pressure. What will be its volume at higher attitude when temperature is 15°C and pressure is 600 mm Hg. |

Answer» (a) Graph (A). (b) \(\frac{p_1V_1}{T_1}\) = \(\frac{p_2V_2}{T_2}\) (c) V2 = \(\frac{p_1V_1T_2}{p_2T_1}\) = \(\frac{760\,mm\,of\,Hg\times700\ mL\times288.15\ K}{600\ mm\ of\ Hg\times298.15\ K} \) = 856.93 mL |
