Question | Answer |
the energy transferred between substances because of a difference in their temperatures | heat |
the state in which two substances that are mixed or touched together reach the same temperature | thermal equilibrium |
the heat energy required to raise the temperature of one kg of a substance by 1 degree celcius or 1K | specific heat |
a measure of the average kinetic energy if the particles (atoms or molecules) in a substance | temperature |
the transfer of heat by means of motion in a fluid | convection |
the process by which heat is transferred when objects at different temperatures are touched together | conduction |
the increase in length or volume of a material when it is heated | thermal expansion |
the natural processes tend to increase the entropy of the universe | 2nd law of thermodynamics |
thermal energy cant be created nor destroyed but can be transformed from one substance to another | 1st law of thermodynamics |
a substance in which heat is easily transferred throughout | thermal conductor |
as the temperature of a substance approaches absolute zero, this entropy and kinetic energy approaches zero | 3rd law of thermodynamics |
