Chapter 18: Q. 18 (page 511)

What is the temperature in $°$ F and the pressure in Pa at the triple point of (a) water and (b) carbon dioxide?

Short Answer

Expert verified

(a) $T_{F} = 32.02 ° F, ρ = 608 P a .$

(b) $T_{F} = - 68.8 ° F, ρ = 5.06 \times 10^{5} P a .$

Step by step solution

Description

Figure 18.6 depicts a water diagram and triple point of water is $0.01 ° C$ as well as the pressure is $= 0.006 a t m$ .

Includign that, Figure 18.6 depicts the diagram of carbon dioxide and triple point of carbon dioxide is $= 56 ° C$ and pressure is $= 5 a t m$ .

Result of finding the pressure and temperature

The equation (18.6) depicts the form of

$T_{F} = \frac{9}{5} T c + 32 °$ (1)

The value of $T_{C} = 0.01 °$ is going to be used into equation (1) in order to get $T_{F}$

$T_{F} = \frac{9}{5} T c + 32 ° = \frac{9}{5} (0.01 °) + 32 ° = 32.02 ° F$

The next formula for calculating the pressure for Pa is:
$p = (0.006 a t m) (\frac{1.01325 \times 10^{5} P a}{1 a t m}) = 608 P a$

The value of $T c = - 56 °$ is going to be used into equation (1) in order to get $T_{F}$

$T_{F} = \frac{9}{5} T c + 32 ° = \frac{9}{5} (- 56 °) + 32 ° = - 68.8 ° F$

The next formula for calculating the pressure for Pa is:
$p = (5 a t m) (\frac{1.01325 \times 10^{5} P a}{1 a t m}) = 5.06 \times 10^{5} P a$
