WALT: Define what heat is and explain the difference between heat and temperature.

Heat is simply the transfer of energy from a hot object to a colder object

Temperature is the warmth or coldness of an object or substance with reference to some standard value. Its various standardized numerical measures are such as the Kelvin, Fahrenheit, and Celsius scale media type="file" key="Measuring Temperature.flv" width="176" height="114" Eureka video; Measuring temperature (5min)
 * Temperature ** Temperature is what the thermometer reads.


 * Celsius scale :** A temperature scale that defines the freezing point of water as 0 degrees and the boiling point of water as 100 degrees. The unit is degree(s) Celsius ( o C). 0° represents the melting point of ice and 100° represents the boiling point of water [ These are two fixed points, called ice point and steam point ].


 * Kelvin scale [Absolute scale] :** The lowest possible temperature that exists in the universe - the absolute zero. The unit is the **kelvin (K)** - SI unit for temperature.

// T // /K = //t///°C + 273

Fahrenheit vs Celsius

 * **°F**, the **Fahrenheit Scale** (used in the US), and
 * **°C**, the **Celsius Scale** (part of the Metric System, used in most other countries)
 * [[image:http://www.mathsisfun.com/images/fahrenheit-celsius.gif width="299" height="190"]] || The conversion formulas between °F and °C are:

[°C] = ([°F] - 32) × 5/9

[°F] = [°C] × 9/5 + 32 || 1) Convert 37°C to Fahrenheit. 37°C x 9/5 + 32 = 98.6°F || 2) Convert 98.6°F to Celsius. (98.6°F - 32) x 5/9 = 37°C ||
