Gas Laws

 

1. A gas has a volume of 600 cm³ at a temperature of 27⁰ C and a pressure of 1 atmosphere. Find its volume at a temperature of 127⁰C and a pressure of 2 atmospheres.400 cm3
2. A fixed mass of gas at constant pressure has a volume of 576 cm³ at 15°C. Find its volume (a) at 0⁰C, (b) at 100⁰C.456,746
3. A fixed mass of gas at constant pressure has a volume of 600 cm³ at 0^°C. At what temperature will its volume be (a) 400 cm³, (b) 1200 cm³? -91 273
4. A uniform glass tube, sealed at one end, contains a column of air trapped by a small pellet of mercury. The length of the air column is 145 mm at 17^°C. Calculate (a) the length of the air column at 47^°C, (b) the temperature at which the air column is 132 mm long. 160 -9
5. A fixed mass of gas exerts a pressure of 715 mmHg at 13°C. If its volume is kept constant, calculate the pressure exerted at (a) 0°C, (b) 100 °C. 682.5 932.5
6. How could you make a gas (a) hotter (b) cooler without supplying or extracting heat energy? Explain why your methods work.
7. A gas at a temperature of 27 °C occupies a volume of 500 cm³ at a pressure of 102 000 Pa. If its temperature increases to 127 ^°C, and its volume to 850 cm', what is the new pressure? 80000
8. A gas at a temperature of 12°C occupies 722.0 cm ³ at a pressure of 750 mmHg. Find its volume at s.t.p. (0⁰C, 760 mm of Hg) 682.5
