Heat VS temperature
Heat VS Temperature
Heat = Thermal energy
Thermal Energy = The total energy of all the particles in a material
Temperature = A measure of the average energy of the particles in a material.
Quiz with Thermal energy
Both cups have coffee that is at a temperature of 80 degrees Celsius.
Which has more heat energy?
If you answered the bigger cup, you are correct because it contains a higher amount of thermal energy than the smaller cup.
There are 3 popular scales for measuring temperature - Celsius, Fahrenheit, and Kelvin
Out of these 3, Celsius is the most common measuring scale
Freezing point of water is at 0 Degrees Celsius
Boiling point of water is at 100 Degrees Celsius
(at sea level)
Kelvin
Scientists use Kelvin to measure the behavior of Gases
To convert Celsius to Kelvin -
Add 273 to Celsius.
For example
Freezing point of water is 273 Kelvin
Boiling point of water is 373 Kelvin
"Absolute Zero" is the coldest possible temperature, and is measured in Kelvin.
Zero Kelvin is -273 Degrees Celsius
Fahrenheit
Formula to convert:
°C = (°F − 32) × 5/9
°F = (°C x 9/5) + 32
Exercise - Convert
How is temperature measured?
- Temperature can be measured using a thermometer.
- Thermometers have sensors which can measure the temperature of a substance
