Thermal Properties of Matter topics include: Eelasticity, elastic limit, stress and strain, streamline and turbulent flow, thermal conductivity and expansion. Thermal properties of matter are based on the idea that the temperature of matter depends on its surroundings and thermal conductivity.  Here are some thermal properties of matter: Specific heat capacity A material's ability to store heat. Water has a high specific heat capacity, making it effective at storing heat. Thermal conductivity A material's ability to conduct heat. This property is independent of the material's shape or...
