Question

1. type the equation for the ideal gas law.
2. the ideal gas law brings together ___ properties.
3. what four variables are used to explain gases?
4. identify all the correct variables that are matched correctly with their unit.

a) amount -> mol
b) volume -> atm
c) temperature -> k
d) pressure -> l

Explanation:

Step1: Recall Ideal Gas Law formula

The Ideal Gas Law is $PV = nRT$.

Step2: Identify number of properties

The Ideal Gas Law brings together four properties: pressure ($P$), volume ($V$), amount of gas ($n$), and temperature ($T$).

Step3: List the four variables

The four variables used to explain gases are pressure, volume, amount (in moles), and temperature.

Step4: Match variables with units

The correct matches are: amount $\to$ mol (A is correct), volume $\to$ L (not atm, so B is incorrect), temperature $\to$ K (C is correct), pressure $\to$ atm (not L, so D is incorrect). So the correct options are A and C.

Answer:

1. $PV = nRT$
2. four
3. pressure, volume, amount (in moles), temperature
4. A. amount $\to$ mol, C. temperature $\to$ K
