Module Two Sample Pretest: Part G
Temperature Conversion 10 points
The general formula
for the conversion of temperatures on scale X to temperatures on scale Y is:
oY
= Y units/ x units ( oX - RPx) + RPy
convert -196oC to oF
convert -196oC to K
The Rankin scale uses a Fahrenheit
unit, but assumes zero to be absolute zero.
If absolute zero on the Kelvin scale is zero and on Celsius scale is
-273oC, calculate absolute zero on the Fahrenheit scale, then
estimate the Freezing point of water on the Rankin scale. (The BP water=212
oF=100
oC=373K= ?R)

A 25.0-mL sample of liquid bromine has
a mass of 78.0 g. What is the density
of bromine?
If a sugar solution weighs 4.678 gram
and has a volume of 4.67 ml, calculate the density of the solution.
