thermal conductivity. n. 1. (General Physics) a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kelvin.
Temperature Definition. Temperature is the property of matter which reflects the quantity of energy of motion of the component particles. There are several scales used to measure this value (e.g., Kelvin, Celsius, Fahrenheit). Examples: The temperature of the solution was 25Â°C.
