Fahrenheit, Celsius & Kelvin
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.
Celsiusa 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.
Kelvinanother 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°

Body Temperature
A Comparison of Temperatures
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.
