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.

Temperature Scales

Fahrenheit, Celsius, and Kelvin.

Reference points for the boiling and freezing points of water.

Temperaturea 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.

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°

37+ degrees Celcius

98+ degrees Fahrenheit

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.

Amazing Facts – Highest recorded Human body Temperature !

• 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.

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.

Death from EcstasyJuly 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.
