# What transformation of energy is formed when you use the electric heater to boil the water?

Contents

An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy.

## What is the energy transformation when boiling a water?

When water is boiled on a stove, the water molecules at the bottom of the pot are closest to the heat source and gain thermal energy first. They begin to move faster and spread out, creating a lower density of molecules at the bottom of the pot.

## What is the energy transformation that occurs in an electric heating system?

Friction (Kinetic energy → Heat) Electric heater (Electric energy → Heat)

## Which energy changes take place when an electric kettle boils water?

Answer: Electrical to heat. Explanation: When you boil water using an electric kettle, it’s an example of electric energy being converted into heat energy.

## What happens to heat energy?

As a form of energy, heat is conserved, i.e., it cannot be created or destroyed. It can, however, be transferred from one place to another. Heat can also be converted to and from other forms of energy.

## What types of energy are in boiling water?

Boiling water is heat energy.

## How electric energy is transformed to thermal energy by an electric current?

The heating element inside every electric heater is simply an electrical resistor, and works on the principle of Joule heating: an electric current through a resistor converts electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element.

## How is heat energy generated into electrical energy?

Thermoelectric materials generate power directly from the heat by converting temperature differences into electric voltage. … Having low thermal conductivity ensures that when one side is made hot, the other side stays cold, which helps to generate a large voltage while in a temperature gradient.

## When electric energy is converted into heat it is called?

The process in which the electrical energy is converted to heat energy is called Electric heating and the heating element inside every electric heater is the resistor. It works on the principle of Joule heating and, thus an electric current passing through the resistor will convert the electricity into heat energy.

## What happens to a kettle of boiling water?

The water inside the kettle boils, evaporates in the form of bubbles and comes out of the spout as steam. Then when the steam makes contact with the cold air outside the kettle, it quickly condenses back to tiny droplets of water which you see as water vapor.

## What is the energy conversion in electric kettle?

Electrical appliances

Appliance Useful energy
Electric kettle Energy that heats the water.
Hairdryer Internal (thermal) energy heating the air. Kinetic energy of the fan that blows the air.
Battery operated torch Light radiation given out by the hot filament of the bulb.

## Which form of energy transfer do you see when water is boiling can this energy transfer apply to water vapor?

Conduction. The stove heats up the pot or kettle the water is in. The heat energy is transferred to the water. Molecules in the water are energized with the transferred heat energy until the boiling point is reached.

## What happens to the water and its thermal energy is heated?

Continued heating of liquid water causes the molecules to vibrate even faster, steadily raising the temperature. FREEZING When liquid water freezes, it releases thermal energy and turns into the solid state, ice. … The result is vaporization— the liquid be-comes a gas.

## What happens when heat is applied to water?

An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. … When water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense.

## Which energy change occurs during boiling some heat energy of the substance is lost heat energy of the substance remains the same most heat energy?

Explanation: When we boil the substance: Energy is provided to the substance during boiling by the means of heating. This heat energy is then absorbed by the substance which results in increase of an internal energy of the substance.
