Question

Use the table below (table 3.2) to find the temperature to which mercury needs to be heated to prevent any change in its volume as it is pressurized at 70 Fahrenheit from 14.7 to 1000 psia. Assume all physical properties are constant for this process.

tips/hint form my teacher:

Because beta is much smaller than kappa, delta_T is going to be really large (over 2500°F)

Explanation / Answer

P1/T1 = P2/T2

T2 = P2/P1*T1 =1000/14.7 * 70 =4761.90 Farhenheit
