Textbook Question
Chapter 7, Problem 1R
Using Table 7-1, list the six different fuel gases in rank order according to their temperature.
Expert Solution & Answer
To determine
List the six different fuel gases in rank according to their temperature according to Table 7-1.
Explanation of Solution
In cutting process various gases are used. Oxyacetylene gas is the most common gas which is used to cut the metal. Some of the other gases are given below according to their temperature given in table 7-1:
| Ranking position | Fuel gases | Temperature ( Celsius ) |
1 | Acetylene | 3087 |
2 | MAPP | 2928 |
| 3 | Propylene | 2868 |
4 | Hydrogen | 2660 |
5 | Natural gas | 2536 |
| 6 | Propane | 2526 |
