Question

Indicate if pressure increase decreases, or stays the same in each of the following: $\left(8.2,8.4,8.6\right)$

Short answer

a. The pressure will increase.

b. The pressure will increase.

c. The pressure will increase.

Step-by-step solution

Part (a) step 1: Given Information

We need to find whether pressure increases, decreases, or stays the same in the diagram.

Part (a) step 2: Explanation

There is no change in the amount of gas and the temperature is constant too.

Therefore from the combined gas law:

$\frac{P_1\times V_1}{T_1}=\frac{P_2\times V_2}{T_2}$

Pressure is directly related to the inverse of volume with decreasing volume pressure will increase.

Part (b) step 1: Given Information

We need to find whether pressure increases, decreases, or stays the same in the diagram.

Part (b) step 2: Explanation

There is no change in the volume of gas and the temperature is constant too.

Therefore from the combined gas law:

$\frac{P_1\times V_1}{T_1}=\frac{P_2\times V_2}{T_2}$

Pressure is directly related to the number of moles with an increasing number of moles pressure will increase too.

Part (c) step 1: Given Information

We need to find whether pressure increases, decreases, or stays the same in the diagram.

Part (c) step 2: Explanation

There is no change in the amount of gas and the volume is constant too.

Therefore from the combined gas law:

$\frac{P_1\times V_1}{T_1}=\frac{P_2\times V_2}{T_2}$

Pressure is directly related to the temperature with increasing temperature will pressure increase too.
