How does specific heat affect heat transfer

WebHeat capacity is the amount of heat required to change the temperature of a given amount of matter by 1°C. The heat capacity of 1 gram of a substance is called its specific heat capacity (or specific heat), while the heat capacity of 1 mole of a substance is called its molar heat capacity. WebAug 18, 2024 · As time progresses, owing to the high temperature gradient near the side you are heating, and the lower temperature gradient further in, the heat penetrates further into the object. The shc determines how much can get stored in this thermal boundary layer, and, overall, the thermal diffusivity determines how far the penetration is at a given time.
