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

Answer:

A) -10°F

Step-by-step 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 $^\circ F$ = $\frac{-2A}{1000}$

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 $^\circ F$ = $\frac{-2A}{1000}$

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 $^\circ F$ =

$\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}$

Therefore, the answer is:

A) -10°F
