Answer:
Volume will decreased by decreasing the amount of gas.
Step-by-step explanation:
The amount of gas and volume are directly related to each other. By decreasing the amount of gas volume will decrease by keeping the temperature and pressure constant.
Mathematical expression:
V ∝ n
V = Kn
we put the K by removing the sign of proportionality.
K = proportionality constant
n = amount of gas
V = volume of gas
The volume- amount relation is called Avogadro law.
By increasing the amount of gas volume will also goes to increase.
