Answer:
Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.
The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.
Thermal energy is defined as the energy present within an object because of the motion of its particles.
So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.
Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.
Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.

The answer is B
Explanation:
Fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.
A fossil fuel is defined as a hydrocarbon consisting of naturally occurring material in the Earth's crust from the remains of dead plants and animals that is extracted and burned as a fuel. The main fossil fuels are coal, oil and natural gas.
The four main types of fossil fuels are
1. Petroleum
2. Coal
3. Natural gas
4. Oil emulsions.
They normally have a variety of physical, chemical and other essential properties. The most unfair thing about fossil fuels is that they are not green. Fossil fuels are made from plants and animals that decompose.
Thus, fossil fuels are made from decomposed plants and animals found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil and natural gas are examples of fossil fuels.

Fossil fuels, like coal, oil, and natural gas, are the primary sources of energy for electricity generation, transportation, heating, and industrial processes, but their use also poses environmental challenges.
The relationship between fossil fuels and energy is foundational to modern society. Fossil fuels, including coal, oil, and natural gas, serve as the primary sources of energy for many aspects of our daily lives and industrial processes. Here's how this relationship works:
1. Energy Generation: Fossil fuels are burned in power plants to generate electricity, which powers homes, businesses, and industries. They are also used as fuels in vehicles, airplanes, and ships for transportation.
2. Heating and Cooling: Fossil fuels are essential for heating homes, providing hot water, and running HVAC systems, ensuring comfort and warmth in colder climates.
3. Industrial Processes: Many industrial processes rely on fossil fuels for heat, steam, and electricity, including manufacturing, chemical production, and refining.
4. Electricity Grid: Fossil fuels play a crucial role in stabilizing the electricity grid, providing reliable power during peak demand.
However, the extensive use of fossil fuels also has environmental consequences, including air pollution, greenhouse gas emissions, and climate change.
As a result, there is a growing emphasis on transitioning to cleaner and more sustainable energy sources like renewable energy (e.g., solar, wind, and hydropower) to mitigate these environmental impacts and ensure a sustainable energy future.
