2. Changes of state (heating curve) Temperature
Thermal energy review (kinetic particle theory): It´s the energy contained in the kinetic movement of all the particles of a substance. Depends on:
The amount of substance
The kinetic energy of all the particles (which can be measured by the temperatura)
Changes of state (heating curve)
Temperature
Definition: Measurement of thermal energy
Scales
Celsius: 0º - 100º based on water freezing and boiling point
Kelvin: absolute scale. Absolute zero: no kinetic movement of the particles : zero Kelvin. = -273 ºC
Farenheit: investigate and write the formula.
Heat: definition: It´s the transfer of thermal energy from one substance to another
Units: 1 cal = 4.18 Joules
Joules (J) and kilojoules (Kj)
Calories (cal) and Kilocalories (Kcal)
Transfer of heat: Types of materiasl: conductos and insulators.
Conduction
Convection
Radiation

4. Heat and temperature
Differences heat and temperature:
Measuring temperature:
What is heat: MsrjBtGL-j
How termometers work and scales: j&index=2
Why America still uses Farenheit?
