    particles either consist of particles that are either hot or cold. High temperature bodies‚ are often caused due to the high heat transfer‚ which is created by chemical reactions‚ nuclear reactions‚ electromagnetic dissipation‚ or mechanical dissipation. Heat is generally transferred between two different objects by radiation‚ conduction and convection. Heat is only passed on between objects‚ with the help of different temperatures.
