Fungus gnats are small, dark, short-lived gnats, of the families Sciaridae, Diadocidiidae, Ditomyiidae, Keroplatidae, Bolitophilidae, and Mycetophilidae (order Diptera); they are sometimes placed in the superfamily Mycetophiloidea. The larvae feed on plant roots and fungi, helping in the decomposition of organic matter.
In each of these situations, you experienced the work of the three types of heat transfer: conduction, convection, and radiation. Conduction, or direct heat, occurs when the faster moving molecules of the fire collide with the cooler molecules of the marshmallow, causing them to move faster and become hot.
Is the most heat lost by the means of conduction, convection or radiation? Asked by: Shazia Answer The three methods of heat transfer can occur in different ratios depending on the materials and environment. Radiation, for example, is the only method by which internal energy can be transferred through a vacuum.
