Does heat transfer increase with temperature difference?

The greater the temperature difference, the greater the rate at which heat transfers. Heat is transferred by one or more of three processes. 1. Conduction, an example of which is having the objects in physical contact. 2. Convection, in which the heat is transferred through a medium, such as air, so it's a slower, much less efficient process. 3. Radiation, which is how the heat of the Sun gets to us through the vacuum of space.
