Thermal energy, temperature, and heat (video) | Khan Academy
Thermal energy refers to the kinetic energy of randomly moving particles in a substance. Particles can have translational, rotational, and/or vibrational kinetic energy, depending on the state of …
What is thermal energy? (article) | Khan Academy
Heat is the flow of thermal energy. A whole branch of physics, thermodynamics, deals with how heat is transferred between different systems and how work is done in the process (see the 1ˢᵗ …
Heat capacity (article) | Khan Academy
Explore how different materials require different amounts of energy to change their temperatures, and how heat capacity impacts real-life situations like cooking and changes in weather.
Heat capacity (video) | Thermodynamics | Khan Academy
The amount of heat gained or lost by a sample (q) can be calculated using the equation q = mcΔT, where m is the mass of the sample, c is the specific heat, and ΔT is the temperature …
Thermal energy and heat transfer (video) | Khan Academy
This transfer of energy between systems is what we call heat. Temperature measures the average kinetic energy or motion of these particles. All matter contains moving particles with …

Dive into the fascinating world of thermal energy and heat! Learn the difference between temperature and heat, discover how thermal energy transfers from hot to cold objects, and …
The laws of thermodynamics (article) | Khan Academy
The release of heat during energy exchanges, combined with the presence of greenhouse gases, acts as a feedback loop, leading to a warming planet and its associated climate changes.
Heat energy (practice) | Heat - Measurement | Khan Academy
Let's solve some questions on heat energy
Specific heat capacity (video) | Khan Academy
The video is comparing the specific heat capacities of water and oil and claiming that oil’s specific heat capacity is less than that of water. Specific heat capacity is defined as the amount of …
Thermal conduction, convection, and radiation - Khan Academy
There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. …
