Sentences with phrase «thermal conductance»
Thermal conductance is a measure of how easily heat can flow through a material. It tells us how well a substance conducts or transfers heat. A high thermal conductance means heat can move easily through the material, while a low thermal conductance means the material is not as effective in transferring heat. Full definition
