In this investigation it is important that I use containers made of the same size, and same shape, with the same volume of water, at the same temperature. This is called 'controlling the variables', which will help me carry out the investigation as accurate as possible. * Theory: The four main types of heat transfer are the following: - Convection involves the movement of molecules and so it can only occur in fluids (liquids and gases), where the molecules can move within the body of the...
