What is meant by the term 'energy transfer'?
Energy transfer refers to the process of moving energy from one place or object to another, such as when energy is transferred from a battery to a lightbulb.
Give an example of energy being transferred by radiation.
An example of energy transferred by radiation is heat from the Sun reaching the Earth.
What happens to the energy when a ball is thrown into the air and then falls back down?
As the ball rises, its kinetic energy is converted into gravitational potential energy. As it falls, the potential energy is converted back into kinetic energy. Some energy is also dissipated as heat due to air resistance.
What is meant by 'dissipation of energy'?
Dissipation of energy refers to the process where energy is lost to the surroundings, often as heat, making it less useful for doing work.
What is the energy conversion that occurs in a kettle when it is switched on?
In a kettle, electrical energy is converted into thermal energy (heat), which is used to heat the water.
Name one advantage and one disadvantage of using wind energy as a power source.
Advantage: Wind energy is renewable and does not produce carbon emissions.
Disadvantage: Wind energy is dependent on weather conditions and may not be reliable.
What is the difference between renewable and non-renewable energy resources?
Renewable energy resources can be replenished naturally in a short period of time (e.g., wind, solar), while non-renewable resources are finite and take millions of years to form (e.g., coal, oil).
What are the two main methods of transferring energy from power stations to homes?
Energy is typically transferred from power stations to homes through high-voltage power lines, and then reduced to a lower voltage using transformers for safe use in households.
What is geothermal energy, and how is it used?
Geothermal energy comes from the heat stored beneath the Earth's surface. It is used to generate electricity or for heating buildings by tapping into hot water or steam reservoirs underground.
What is the role of a heat exchanger in a power plant?
A heat exchanger transfers thermal energy from one fluid to another. In a power plant, it is used to transfer heat from the hot steam to a secondary fluid, which can then drive turbines to generate electricity.
