$\%$ PLEASE READ ALL THE LOCKED COMMENTS CAREFULLY BEFORE SUBMITTING ANY ANSWERS.

$\%$ IF YOU DO NOT READ THESE COMMENTS, YOU ARE LIKELY TO OVERLOOK AN IMPORTANT DETAIL

$\%$ OF THE REQUIRED SUBMISSION STYLE.

$\%$ Import your data and make any preliminary calculations between here and the next

$\%$ set of locked lines.

$\%$ Create your Boyle's Law plot between here and the next set of locked lines.

F$1=$ figure$(1)\%$ create a figure handle called F$1,$ for checking your answers

$\%$ make sure your figure has a legend or MATLAB Grader will not grade your work correctly.

$\%$ Plot your Gay$-$Lussac's Law figure between here and the next set of locked lines.

F$2=$ figure$(2)\%$ create a figure handle called F$2,$ for checking your answers

$\%$ make sure your figure has a legend or MATLAB Grader will not grade your work correctly.

$\%$ Perform the rest of your calculations below this locked line.

$\%$ Define the Excel file name

filename $=$ 'Raw$\_$Data.xlsx$\text{'}$;

$\%$ Read data from each sheet

$\%$ Make sure the sheet names match exactly with those in the Excel file

data$\_$air $=$ readtable$($filename$,$ 'Sheet', 'Air'$)$;

data$\_$co$2=$ readtable$($filename$,$ 'Sheet', $\text{'}$CO$2\text{'})$;

data$\_$n$2=$ readtable$($filename$,$ 'Sheet', $\text{'}$N$2\text{'})$;

$\%$ Example: Assuming the first column is temperature and the rest are pressures

$\%$ Convert temperatures from Celsius to Kelvin

temperatures$\_$air $=$ table$2$array$($data$\_$air$($:$,1))+273\mathrm{.}15$; $\%$ Celsius to Kelvin

$\%$ Assuming the first row is volume and the rest are pressures

$\%$ Extract volumes $($assuming they are in the first row$)$

volumes $=$ data$\_$air.Properties.VariableNames$(2$:end$)$; $\%$ Variable names from the second column onwards

$\%$ Boyle's Law for Air: P vs V at constant T

$\%$ You would use specific rows for specific temperatures

$\%$ This is just an example, you need to modify it to match your data

F$1=$ figure$(1)$;

hold on;

for i $=1$:$3\%$ Assume we are plotting for first three temperatures

P$\_$air $=$ table$2$array$($data$\_$air$($i$,2$:end$))$; $\%$ Pressure values for a specific temperature

V $=$ str$2$double$($volumes$)$; $\%$ Convert volume strings to numbers

plot$($V$,$ P$\_$air, $\text{'}-$o$\text{'},$ 'DisplayName', $[\text{'}$T $=\text{'}$ num$2$str$($temperatures$\_$air$($i$))\text{'}$ K$\text{'}])$;
