1. Temperature
Temperature
 Is a measure of how hot or
cold an object is compared to
another object.
 Indicates that heat flows from
the object with a higher
temperature to the object with
a lower temperature.
 Is measured using a
thermometer.

2. Temperature Scales
 Fahrenheit,
Celsius, and
Kelvin.
 Reference points
for the boiling
and freezing
points of water.

3. Temperature
a measure of how hot or cold something is
• Celsius = a unit of temperature in the
metric system
• Water freezes at 0° C.
• Water boils at 100° C.
• Normal body temperature is 37° C
• Room temperature is 21° C.

4. Temperature
(continued)
• Kelvin = another unit of temperature in
the metric system.
• The lowest possible temperature is
0 Kelvin (-273 ° C). This is Absolute Zero.
• To convert from Celsius to Kelvin:
K = C + 273°

7. How much can we take?
Body temperatures above 40 °C (104 °F)
are life-threatening. At 41 °C (106 °F),
brain death begins, and at 45 °C (113 °F)
death is nearly certain. Internal
temperatures above 50 °C (122 °F) will
cause rigidity in the muscles and certain,
immediate death.

8. Amazing Facts – Highest recorded Hu
• Did you know, that the highest recorded human
body temperature was : 115.7oF (46.5oC)
• Very amazingly, the guy survived to talk (and
brag) about it.
• According to the Guinness Book of World Records
(New York: Bantam Books, 2000, p. 263), the
person with the highest body temperature who
lived to tell about it is Willie Jones. On July 10,
1980, Mr. Jones was admitted to the hospital with
heatstroke. His temperature was 115.7oF
(46.5oC). After 24 days in the hospital, he was
discharged.

9. The lowest recorded body
temperature with a full recovery was
56.6 degrees Fahrenheit, (13.7
degrees centigrade). This was the
temperature of Anna Bagenholm who
found herself trapped under ice for 80
minutes in May 1999 while skiing with
friends in Norway.

10. Death from Ecstasy
July 13, 2001
A student died with a look of "sheer fright“
on her face after taking an unusually
high-strength ecstasy tablet.
Paramedics who tried to save 19-year-old
Lorna Spinks said her eyes were wide open
and her tongue was sticking out as they took
her to hospital. By the time Miss Spinks
arrived at Addenbrooke's Hospital she had a
temperature of 43 degrees Celsius (109.4F) –
the normal level is 37 degrees Celsius
(98.6F). The drug had thinned Miss Spinks'
blood so that she was bleeding profusely
internally and externally.
