Question 169

In a high-pressure experimental chamber, the relationship between Temperature, TTT, and Pressure, PPP, is modeled by the implicit equation:

T2−10T=2P2−16P+5 T^2 - 10T = 2P^2 - 16P + 5 T2−10T=2P2−16P+5
a.

Find an expression for dTdP\frac{dT}{dP}dPdT​ in terms of TTT and PPP.

[3]
b.

The model predicts that temperature TTT has no real solutions for pressure values in the interval (p,q)(p, q)(p,q). Use your result from part (a) or otherwise to determine the value of ppp and the value of qqq.
