 Indicates that heat flows from the object with a higher temperature to the object with a
lower temperature.
 Is measured using a thermometer.

Celsius = a unit of temperature in the metric system
Water freezes at 0&deg; C.
Water boils at 100&deg; C.
Normal body temperature is 37&deg; C
Room temperature is 21&deg; C.
Kelvin = another unit of temperature in the metric system.
The lowest possible temperature is
0 Kelvin (-273 &deg; C). This is Absolute
Zero.
To convert from Celsius to Kelvin:
K = C + 273&deg;
Body Temperature
37+ degrees Celsius
98+ degrees Fahrenheit
Body temperatures above 40 &deg;C (104 &deg;F) are life-threatening. At 41 &deg;C (106 &deg;F), brain
death begins, and at 45 &deg;C (113 &deg;F) death is nearly certain. Internal temperatures
above 50 &deg;C (122 &deg;F) will cause rigidity in the muscles and certain, immediate
death.
