Select the type of energy involved in each step.

you turn on the burner of a gas stove. a) chemical b) thermal c) mechanical d) electrical

the gas ignites. a) chemical b) thermal c) mechanical d) electrical

the gas warms the water in the pan. a) chemical b) thermal c) mechanical d) electrical

Explanation:

1) When we turn on the burner of the gas stove, we use mechanical energy. Mechanical energy is energy due to motion of an object.

Correct is option (c).

2)The ignition of the gas is a chemical energy. Chemical energy is is a energy which releases during the chemical reaction. Here gas id reaction with air to get ignite.

Correct is option (a).

3) The warming of the water in the pan by the help of burning gas is thermal energy. The thermal energy is an energy due to motion of the molecules or particles which can be transferred from one object to another in form of heat. Here the heat transferred to the pan by the burning of gas warms the water.

Correct is option (b).
