In this section, we will explore three popular types of t-shirt transfers: Heat Transfer Vinyl, Inkjet Transfer Paper, and Sublimation Transfers. The heat capacity is a constant that tells how much heat is added per unit temperature rise. The value of the constant is different for different materials. Heat is always transferred from the object at the higher temperature to the object with the lower temperature. For a gas, the heat transfer is related to a change in temperature.Whenever there is a temperature difference, heat transfer occurs. Heat transfer may happen rapidly, such as through a cooking pan, or slowly, such as through the walls of an insulated cooler. There are three different heat transfer methods: conduction, convection, and radiation. At times, all three may happen simultaneously. See Figure 11.3.In summary, when you grill, the main heat transfer method is conduction. Convection and radiation also play a role, but to a lesser extent.
