Contrast the energy transformation that occur in a electrical toaster oven and in an electrical fan.

The electrical toaster oven and electrical fan are commonly used household appliances that include the conversion of energy from electrical to heat energy.

The toaster oven is used to toast the slices of bread and it warms the food releasing heat energy by the use of electrical energy.

Similarly, the fans are also designed in such a way that it initially converts the electrical energy to kinetic energy as the blades of the fan rotates. Due to this rotating blades again there occurs another type of energy in the fan's motor known as the heat energy as the blades are connected to the motor.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
