Hello, I am having trouble plotting this graph. Whenever I run my code I get an error that I am not using the plot function correctly or I get a blank graph. I think it may have to do with how I solved my equation for T. Thanks for any help.

To = 273
Pair = 400000
Vo = .00066667
cp = 1
syms T t
T = To - (Pair*((Vo*((T/To)^(-5/2))) - Vo)/cp)*t;
Eqn = solve(T, t)
t = 0:.001:1;
Teq = Eqn
plot(t,Teq)

The only equation that I have for T is [T = To - (Pair*((Vo*((T/To)^(-5/2))) - Vo)/cp)*t]. Because T is on both sides of the equation I used syms to solve the equation so it is just an equation of T(temp) with respect to t(time). Then I want to graph the plot of time (t) vs Temp (T).

You are using the wrong plot function.
Use fplot instead:
fplot(Teq,[0 1])
xlabel('t')
ylabel('Teq')
