Question

STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet

A) -10°F B) 20°F C) 10°F D) -20°F

Answer 1

A) -10°F

Explanation:

Given that:

Boiling point of water gets affected when there is a change in the elevation.

Expression to represent the temperature i.e. boiling point w.r.to altitude
`A` is given by the equation:

Temperature in
`^\circ F` =
`(-2A)/(1000)`

Given that, the altitude,
`A` = 5,000 feet

To find:

The number of degrees Farenhite at which the boiling point of water will change.

Solution:

Here, we are given the expression:

Temperature in
`^\circ F` =
`(-2A)/(1000)`

And value of altitude,
`A` = 5,000 feet

Let us put the value of
`A` in the equation and let us find the value of temperature in
`^\circ F`.

Temperature in
`^\circ F` =

`(-2* 5000)/(1000)\\\Rightarrow -2* 5\\\Rightarrow \bold{-10^\circ F}`

Therefore, the answer is:

A) -10°F
