Boyle's Law
 1) Which of the following is incorrect in consideration of molecular packing among the three states of matter? Solid molecules are packed as closely together as possible. Liquid molecules are in between gas and solid molecules. All of the above statements are correct. Gas molecules are packed loosely

 2) Which are the fundamental macroscopic properties of gases ? Pressure, temperature and internal energy Pressure, volume, temperature and mass of the gas Pressure, temperature and volume Pressure, volume and mass of the gas

 3) Which variable among the following is constant in Boyle’s Law? Pressure Temperature None of the above Volume

 4) What is the relation between pressure and volume according to Boyle’s Law? Pressure is independent of volume None of these Pressure is inversely proportional to volume Pressure is directly proportional to volume

 5) Which of following pair of variables is inversely proportional to each other under constant temperature? P, T P, V n, T n, V

 6) Which is the correct relation? V = 1/P All of these P1/ P2 = V2/ V1 PV = constant

 7) Which of the following shows the application of Boyle’s Law? Tires Syringes Rockets Both a and c

 8) A 17.50ml sample of gas is at 4.500 atm. What will be the volume if the pressure becomes 1.500 atm. with a fixed amount of gas and temperature? 5.83 ml 52.5 ml 58.3 ml None of these

 9) What is the nature of graph between pressure and volume for a gas at constant temperature? Parabola Hyperbola No fixed shape Straight line

 10) If, at constant temperature, the volume of a flask equipped with a moveable piston is reduced to 1/4 its original volume, what must happen to the pressure? It is increased by a factor of four. It is increased by a factor of eight. It is reduced to 1/8 the original pressure. It is reduced to 1/4 the original pressure.
