Q. 8.6 - An Introduction to General, Organic, and Biological Chemistry

Question

Which of the following statement describes the pressure of a gas?
a. the temperature of the gas
b. the volume of the container
c. $3.0$ atm
d. $0.25$ mole of ${\mathrm{O}}_2$
e. $101$ kPa

Step-by-Step Solution

Answer

Part(a) statement does not describes the pressure of a gas 

Part(b) statement does not describes the pressure of a gas

Part(c) statement describes the pressure of a gas 

Part(d) statement does not describes the pressure of a gas 

Part(e) statement describes the pressure of a gas

Part(a) Step 1 : Given information

We are given statement the temperature of the gas

Part(a) Step 2 : Simplify

As we know pressure is force per unit area, therefore temperature of gas can't be pressure.

Part(b) Step 1 : Given information

We are given statement the volume of the container

Part(b) Step 2 : Simplify

As we know pressure is force per unit area, therefore volume of container can't be pressure.

Part(c) Step 1 : Given information

We are given statement $3.0$ atm

Part(c) Step 2 : Simplify

As we know atm is unit of pressure. Therefore, statement shows pressure.

Part(d) Step 1 : Given information

We are given statement $0.25$ mole of $O_2$

Part(d) Step 2 : Simplify

As we know pressure is force per unit area, therefore number of moles can't be pressure.

Part(e) Step 1 : Given information

We are given statement $101$kPa

Part(e) Step 2 : Simplify

As we know kPa is unit of pressure therefore, statement shows pressure of gas.
