1. Thermometer -is a device used to measure temperature.
•Common Temperature Scale:
-Celsius (degree centigrade) –
Anders Celsius (1701-1744) a Swedish Astronomer
-Fahrenheit Scale
Gabriel Daniel Fahrenheit (1686-1736) a German
Scientist
-Kelvin Scale (absolute temperature scale)
Lord Kelvin William Thompson (1824-1907)
4. To transform one temperature scale to another, the following equations are used.
Celsius to Fahrenheit oF = 1.8 (oC) + 32
Kelvin to Fahrenheit oF = 1.8 (K – 273) + 32
Fahrenheit to Celsius o
C = 5/9 (o
F – 32)
Celsius to Kelvin K = oC + 273
Kelvin to Celsius oC = K – 273
Fahrenheit K = 5/9 (oF – 32) +273
to Kelvin
5. 1.) Mercury is a toxic, liquid metal at room
temperature. It has a very high density and as
such most objects float on mercury including
cannonballs and bricks. The boiling point of
mercury is 355 oC. Determine its boiling point
in (a) oF and (b) K.
Example Problems:
6. 2.) An air conditioner is set to
maintain a room at a temperature
of 240oC. What will be the
corresponding temperature in
(a) Fahrenheit, (b) Kelvin?
7. 3.) Dry ice is -78 oC. What is the
temperature in Fahrenheit?
8. 4.) One of the elements that exist as
gas a room temperature is nitrogen.
The melting point of nitrogen is -320.15
F. Determine its melting point in (a) oC
and (b) K.
9. 5.) The average normal body
temperature is 98.6 oF. What is it in
(a) Celsius, and (b) Kelvin?
10. 6.) The body temperature of a cat
is 101.5 oF. Find this temperature in
Celsius.
11. 7.) In many ideal gas problems,
room temperature is considered
to be at 300 K. What is this
temperature in Celsius?
12. 8. The average body temperature
of a person is 98.6 K. What is the
average body temperature of a
person in Fahrenheit?
13. 9. Room temperature is often used
in calculations as 300 K. What is
the temperature in Fahrenheit?
