The incomplete table below shows a comparison of the different gas laws.
\begin{tabular}{|l|l|l|l|}
\hline Name & Variables & Constants & Equation \\
\hline Boyle's law & pressure, volume & ? & $P_1 V_1=P_2 V_2$ \\
\hline Charles's law & volume, temperature & ? & $\frac{V_1}{T_1}=\frac{V_2}{T_2}$ \\
\hline ? & temperature, pressure & volume, moles of gas & $\frac{P_1}{T_1}=\frac{P_2}{T_2}$ \\
\hline ? & pressure, temperature, volume & ? & $\frac{P_1 V_1}{T_1}=\frac{P_2 V_2}{T_2}$ \\
\hline
\end{tabular}
What is assumed to be constant when using the combined gas law?
A. pressure
B. number of moles
C. volume and moles of gas
Answer (3)
6 days each week and 8 hours each day so total hours = (6x8) = 48 hours.
he earned $360 in a week it means he earn that much money working 48 hours so he paid in one hour is (360/48) = $7.5 (ans)
$7.50 because 6x8 equals 48 and 360 divided by 360 equals $7.50
Andrew worked 48 hours in a week and earned $360. Dividing his total earnings by the total hours gives an hourly wage of $7.50. Therefore, he was paid $7.50 for each hour of work.
