"Dental technologists use basic math a fair bit," says dental technologist
Blaine Pardy. "It's not too complex, but we need to know temperature
conversions and metric conversions."
You've just completed some
bridge work, and are getting ready to construct a new apparatus. The lab has
ordered new materials for you to use. You always have to be prepared to try
new technology and materials that are harder, stronger and better looking.
For this next piece you will be using a new type of plastic and a ceramic.
Part
A
Much of the material you use must be heated to high temperatures
so it becomes pliable and easy to work with. However, to do a proper job,
you must select the right temperature.
You read the guidelines for
the new type of plastic. It should be heated to 212 degrees Fahrenheit. However,
in the lab you measure temperatures in Celsius. What temperature should you
heat the plastic to in degrees Celsius?
Part B
After
you have used the plastic, you must heat the ceramic to a whopping 7,232 degrees
Fahrenheit in order to make it soft. How many degrees Celsius is this?
Equation
Degrees
Fahrenheit - 32 x 5 / 9 = degrees Celsius
