6 Answer true or false. (a) For a sample of gas at constant temperature, its pressure multiplied by its volume is a constant. (b) For a sample of gas at constant temperature, in- creasing the pressure increases the volume. (c) For a sample of gas at constant temperature, P,/V, = P,/V,. (d) As a gas expands at constant temperature, its volume increases. (e) The volume of a sample of gas at constant pressure is directly proportional to its temperature-the higher its temperature, the greater its volume. (f) A hot-air balloon rises because hot air is less dense than cooler air. (g) For a gas sample in a container of fixed volume, an increase in temperature results in an increase in pressure. (h) For a gas sample in a container of fixed volume, PX T is a constant. (i) When steam at 100°C in an autoclave is heated to 120°C, the pressure within the autoclave reases. (j) When a gas sample in a flexible container at constant pressure at 25°C is heated to 50°C, its volume doubles. (k) Lowering the diaphragm causes the chest cavity to increase in volume and the pressure of air in the lungs to decrease. (1) Raising the diaphragm decreases the volume of the chest cavity and forces air out of the lungs.
