Question

Identify the property of a gas that is measured in each of the following:

1. $425K$
   
2. $1.0atm.$
   
3. $10.0L$
   
4. $0.50$mole of$\mathrm{He}$
   

Short answer

Property of a gas that is measured in each of the following are:

(a) Temperature

(b) Pressure

(c) Volume

(d) Amount

Step-by-step solution

Part (a) Step 1: Given Information

We need to identify the property of a gas that is measured as$425K$

Part (a) Step 2: Explanation

As property measured has unit of measurement as $K$. Hence, measured quantity is temperature. It is denoted by $T$. It is determining factor of kinetic energy of gas molecules.

Part (b) Step 1: Given Information

We need to identify the property of a gas that is measured as$1atm$

Part (b) Step 2: Explanation

As property measured has unit of measurement as $atm$. This unit defines force exerted by gas against wall of container. Hence, measured quantity is pressure. It is denoted by$P$.

Part (c) Step 1: Given Information

We need to identify the property of a gas that is measured as$10.0L$

Part (c) Step 2: Explanation

The measured quantity $10.0L$defines space occupied by gas and $L$is unit of measurement of volume. Hence, property is volume. It is denoted by$V$ .

Part (d) Step 1: Given Information 

We need to identify the property of a gas that is measured as$0.50$mole of$\mathrm{He}$

Part (d) Step 2: Explanation

The measured quantity $0.50$mole defines quantity of gas. It is unit of amount. Hence, property of gas measured in amount. It is denoted by$n$.
