thermal load definition, thermal load meaning | English dictionary 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.

General Astronomy/Print version Definition of Thermal Conductivity. Thermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.

Thermal Energy Definition of Thermal Energy. Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules.The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.hile a hot object has greater thermal energy than a cold object of the same type (for example, a hot brick versus a cold brick), it is possible for a large cold object, such as a mountain lake, to have more thermal energy than a small hot object, such as a cup of boiling water.

Thermal conductivity Thermal conductivity (often denoted k, λ, or κ) is the property of a material to conduct heat. It is evaluated primarily in terms of the Fourier's Law for heat conduction. In general, thermal conductivity is a tensor property, expressing the anisotropy of the property.

Understanding Thermal Conductivity Understanding Thermal Conductivity. Thermal Conductivity: A measure of the ability of a material to transfer heat. Given two surfaces on either side of a material with a temperature difference between them, the thermal conductivity is the heat energy transferred per unit time and per unit surface area, divided by the temperature difference [1].

Thermal analysis Thermal analysis. Thermal analysis is a branch of materials science where the properties of materials are studied as they change with temperature. Several methods are commonly used – these are distinguished from one another by the property which is measured: Dielectric thermal analysis (DEA): dielectric permittivity and loss factor.

- Mike McCune/Flickr. Definition: A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. This is the standard measurement used to state the amount of energy that a fuel has as well as the amount of output of any heat generating device. You might be able to imagine it this way.
