Answer» Answer: Conduction: The body should be in contact with difference in temperature.Convection:The body should not be in contact Both conduction and convection require matter to transfer heat. If there is a temperature difference between two SYSTEMS heat will always find a way to transfer from the higher to lower system. CONDUCTION-- Conduction is the transfer of heat between substances that are in DIRECT contact with each other.next questionFor example, rock is more dense than water because a given volume of rock has more mass than the same volume of water. When a liquid or gas is HEATED, the PARTICLES move FASTER and spread apart. As a result, the particles of the heated fluid occupy more space. The fluid's density decreases |
