The correct answer to this question is C, Electric to thermal. Electric toasters are used in many homes to make toast, waffles, and frozen pastries. A toaster transfers electric energy taken from the electrical outlet into thermal energy, which is heat.
In the toaster, there are filaments, also known as wires, which turn red. They do this because that is the heat which warms the toast, waffles, and pastries. These filaments get very hot and shouldn't be touched. While all toasters cook quickly, the higher the watt rating on the toaster, represents, the faster it can heat and cook the food.
C is the answer to this question. A toaster needs to be connected to electricity so that it will start working. The moment that it gets enough electricity, it will start to heat up and that is thermal energy. It is through the heat that the certain food products placed in the toaster may become toasted and even cooked.
Some people who may not have any access to pots, pans, or an electric or gas range, may sometimes use the toaster in order to heat or even cook their food. This is definitely a piece of equipment that you should have in your kitchen because it is highly versatile.
