Bite-sized Thermal Concepts Study Notes for IB Physics HL/SL
The particle model of matter states that all matter is composed of small particles.
There are three types of states:
In a solid, particles can be modeled by springs. The strings represent bonds.
In a liquid, particles will take the shape of the container they are placed in.
Gas is the least dense state of matter.
Temperature is a measure of ‘hotness’ or ‘coldness’ of a body.
T (in Kelvin, K) = T (in degrees Celsuis, C) + 273
A Thermometer is used to measure temperature.
Heat is the energy that is transferred from one body to another body as a result of a difference in temperature.
Formula Booklet
Specific Heat Capacity is the amount of energy needed in order to increase a unit of mass of the object by one kelvin.
Change of phase happens at a constant temperature.
Formula Booklet
Specific Latent Heat (l) is defined as the amount of energy required to change the phase of a unit mass at a constant temperature.
