Science Coursework Investigating Cooling Hypothesis What do I already know Energy is transferred from atom to atom along the bar. At the hot end, the atoms are vibrating a lot. As they bump into each other, the energy is passed along the bar. Heat Transfer For heat to flow from A to B, A must be at a higher temperature than B. Heat energy causes gas and liquid molecules to move around faster, and causes particles in solids to vibrate more rapidly. When particles move faster it shows up as a rise in temperature. This extra kinetic energy in the particles tends to get dissipated to the surroundings. In other words the heat energy tends to flow away from a hotter object to its cooler surroundings. If there's a difference in temperature between two places then heat will flow between them. Conduction Is the transfer of energy (heat) between materials in contact it happens mostly in solids,...
