a) What happens to the size of a gas bubbles rising from the bottom of a water body. Why? b) Which is the gas law associated with this? c) Write the mathematical expression of this law?
Answers
Answer:
Answer:
(a) Pressure starts decreasing as we go upwards . That is the reason that air bubble in water grow in size when it rises from bottom to top. As the pressure exerted by water is directly proportional to the depth of water, as the depth of water increases in a water body, the pressure increases linearly.
(b) This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.
(c) This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant.
