Question

use this diagram to answer the following questions. 4th attempt part 1 (1 point) from the graph, estimate the normal boiling - point of substance x part 2 (1 point) from the graph, estimate the normal boiling - point of substance y

Explanation:

Step1: Recall boiling - point definition

The normal boiling - point is the temperature at which the vapor pressure of a substance is equal to 1 atm.

Step2: Locate 1 atm on the graph

Find the 1 - atm mark on the vapor - pressure axis (y - axis).

Step3: Find the intersection for substance X

Find the intersection of the 1 - atm line with the curve of substance X. Then read the corresponding temperature on the x - axis. From the graph, for substance X, the normal boiling point is approximately 35.0 °C.

Step4: Find the intersection for substance Y

Find the intersection of the 1 - atm line with the curve of substance Y. Then read the corresponding temperature on the x - axis. From the graph, for substance Y, the normal boiling point is approximately 55.0 °C.

Answer:

Part 1: 35.0 °C
Part 2: 55.0 °C
