Could you please help me with the plotting of graphs in thermodynamics

One of the most commonly studied examples of a thermodynamic system is a

piston$-$cylinder engine where the following steps take place: $($Initially$,$ you may

assume that the cylinder contains a fixed quantity of air and a negligibly small

quantity of fuel.$)$

a$.$ The small amount of fuel burns and releases a lot of energy $($heat is

added to the system$)$; assume this takes place in $5$ seconds.

b$.$ The piston gets displaced until the pressure reaches atmospheric

pressure; assume this takes place over $30$ seconds.

c$.$ The gases present in the cylinder are exhausted into the atmosphere;

assume this takes place over $10$ seconds.

Plot the following curves qualitatively:

i$.$ Temperature vs$.$ Time

ii$.$ Pressure vs$.$ Time

iii. Volume vs$.$ Time

iv$.$ Pressure vs$.$ Volume

v$.$ Pressure vs$.$ Temperature

vi$.$ Volume vs$.$ Temperature
