a creatinine urine test measures the amount of creatinine in your urine and can help your doctor evaluate how well your kidneys filter waste this is useful in diagnosing or ruling out kidney diseases and some other conditions
Therefore, to change the energy of a system, energy must be transferred to or from the system. Heat and work are the only two mechanisms by which energy can be transferred to or from a control mass. Heat is the transfer of energy caused by the temperature difference.emperature is used as a measure of the internal energy or enthalpy, that is the level of elementary motion giving rise to heat transfer. Heat can only be transferred between objects, or areas within an object, with different temperatures (as given by the zeroth law of thermodynamics).
Thermal conduction is the transfer of internal energy by microscopic diffusion and collisions of particles or quasi-particles within a body or between contiguous bodies. The microscopically diffusing and colliding objects include molecules, atoms, electrons, and phonons.onduction is the most significant means of heat transfer within a solid or between solid objects in thermal contact. Conduction is greater in solids because the network of relatively close fixed spatial relationships between atoms helps to transfer energy between them by vibration.
