Question

Water freezes at 0 degrees Celsius, which is the same as 32 degrees Fahrenheit. Also water boils at 100 degrees Celsius, which is the same as 212 degrees Fahrenheit. (Use fractions in your answers.)

(a) Use the freezing and boiling points of water to find a
formula expressing Celsius temperature *C* as a linear
function of the Fahrenheit temperature *F*.

(b)This means that for every one degree increase in the Fahrenheit temperature, the Celsius temperature will increase by what degree?

Answer #1

(1)You work in a materials testing lab and your boss tells you
to increase the temperature of a sample by 45.2 ∘C . The only
thermometer you can find at your workbench reads in degrees
Fahrenheit. Part A If the initial temperature of the sample is 66.8
∘F, what is its temperature in degrees Fahrenheit when the desired
temperature increase has been achieved?
(2)
Like the Kelvin scale, the Rankine scale is an absolute
temperature scale: Absolute zero is zero...

The change in temperature in Kelvin and Celsius is the same, as
it should be.
QUESTION Which represents the larger temperature
change, a Celsius degree or a Fahrenheit degree?
It's subjective and depends on the observer's judgment.One
degree is the same on either scale. It
depends on the initial temperature.FahrenheitCelsius

You have a glass of water at 83 degrees C. You want to boil it
by putting it in a vacuum. What is the smallest percentage of air
molecules you would have to remove from the vacuum chamber to allow
it to boil? Hint: to boil, the vapor pressure of water must be
equal to the external pressure. (You will have to refer to a chart
to figure out the vapor pressure of water at 83 degrees).
(Remember, atmospheric pressure...
