Question

Jane puts some water into an electric kettle and then she connects it to the power source. She observes that after some time the water inside the kettle heats up and begins to boil. What is happening? A) Light energy is transforming into heat. Eliminate B) Heat energy is transforming into electricity. C) Electrical energy is transforming into heat energy. D) Electrical energy is transforming into light and heat energy.

Answer 1

Answer: The correct answer is option C.

Explanation:

Electrical energy is an energy possessed by the electrical charges in motion.

Heat energy is an energy due to the motion of particles like atoms, ions etc in solid , liquid and gases .

In an electric kettle:

Electric energy → Heat energy   (Law of conservation Energy)

In an electric kettle electric energy is changing into heat energy which results in heating up of water present in side it.The electric energy from the power source is transforming into heat energy which gets transferred to water molecules.

Hence, the correct answer is option C.

Answer 2

C) electrical energy is transformed into heat energy
