Match the following columns. Column I Column II (i) pressure (a) atmospheric pressure low (ii) At high altitude (b) gas variables (iii)Kelvin zero (c) molecular motion ceases

(i) pressure -- (b) Gas variables Boyle's Law is a Gas Law which states that the pressure exerted by a gas of given mass at constant temperature, is inversely proportional to the volume. (ii) At high altitude-- (a) atmospheric pressure low As altitude rises, air pressure drops. As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. (iii) Kelvin zero -- (c) molecular motion ceases At absolute zero the molecular motion of gases ceases to zero because, at this point volume of gases become zero. Column I Column II (i) pressure (b) gas variables (ii) At high altitude (a) atmospheric pressure low (iii)Kelvin zero (c) molecular motion ceases
