If #18 L# of a gas at room temperature exerts a pressure of #15 kPa# on its container, what pressure will the gas exert if the container's volume changes to #27 L#?

Answer 1

Use Boyles Law.

Boyles Law is the mathematical statement that pressure and volume are inversely related, meaning that when a gas's pressure rises, its volume falls.

#P_1V_1 = P_2V_2#

In this problem, #P_1 = 15kPa#, #V_1=18L#, #P_2=?# and #V_2=27L#

#(15)(18)=P_2(27)#

Split each side by 27.

#P_2 = (15*18)/27#

#P_2=10kPa#

( P_1 \times V_1 / T_1 = P_2 \times V_2 / T_2 )

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
