Expansion of Steam

When water alters to vapor, its volume rises rapidly. At a normal atmospheric pressure of 14.7 pounds per square inch, water boils at 212 levels Fahrenheit and expands in volume by a aspect of 1700 to 1. But once water is sprayed right into hotter locations, the growth proportion is a lot higher. This principle can be used to excellent effect in fire fighting. The heavy steam can occupy such a huge volume that oxygen is expelled from the area and also the fire may be smothered. The table listed below reflects the approximate volume, in cubic feet, of 50 gallons of water converted to steam at the given temperatures, in levels Fahrenheit.

*

a. Make a linear model of volume V as a role of T.

You are watching: 1 gallon of water converted to steam

b. If one fire is 100 degrees hotter than another, what is the increase in the volume of vapor developed by 50 gallons of water?

c. Calculate V(420) and also explain in useful terms what your answer means. Round your answer to the nearemainder entirety number.

d. At a particular fire, 50 gallons of water increased to 14,200 cubic feet of heavy steam. What was the temperature of the fire?
