Detailed explanation-1: -The toaster consist of the heating element. When electrical energy passes through this heating element, it converts this electrical energy to heat energy which helps to prepare toast (bread that turns brown on exposure to heat). Hence electrical energy is transformed to heat energy in a electric toaster.

Detailed explanation-2: -Answer and Explanation: Electrical energy is converted into thermal energy and light energy inside a toaster.

Detailed explanation-3: -Resistors convert electrical energy to thermal energy, and thermoelectric devices convert thermal energy to or from electrical energy.

Detailed explanation-4: -The heating element then transfers ths energy into thermal energy, which heats up the coils in the toaster to toast the bread via conduction.

Detailed explanation-5: -With the students, discuss how the toaster cooks the bread. (It transforms electrical energy into heat energy. The intense heat toasts the bread by producing a chemical change in the toast.)
