Law of Conservation of Energy

Front

What is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, typically occurring in solids and liquids.

Front

How does particle arrangement affect conduction in gases?

Back

In gases, particles are farther apart and move faster, making conduction less efficient compared to solids and liquids.

Front

What happens to heat during conduction?

Back

Heat travels from the hotter object to the cooler object.

Front

What type of energy does a light bulb convert electrical energy into?

Back

A light bulb converts electrical energy into light energy and heat energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules.

Front

What happens to chemical energy when wood burns in a fireplace?

Back

The stored chemical energy in the wood is transformed into heat and light energy.

Front

What type of energy conversion occurs when gasoline is burned in a car engine?

Back

Chemical energy is converted into mechanical energy.

Front

What is an example of energy transformation in a light bulb?

Back

Electrical energy is transformed into light energy and heat energy.

Front

What is the role of heat in energy transfer?

Back

Heat is the energy that is transferred from one object to another due to a temperature difference.
