Feel the heat with these Science Heat Energy Worksheets with Answer

Summary: Energy is the capability of a system to run. Heat is the energy flow from a warm matter to a colder one. Heat energy can be the fuel of a work. It is one of the essential types of energy for daily human life. We use it for cooking, ironing, heating food, and drying hair. We can transfer heat in three ways, convection, conduction and radiation.

What is Energy?

Energy is a common term that we hear every day and everywhere. However, what is energy? Many experts agree that it is a difficult question to answer. There are many types of answers to this question. According to American Petroleum Institute (API), energy is the capability of a system to run. The system can be in a vehicle, human, or natural forces. Energy will cause the vehicle to move, the human to grow, and nature to flourish. We cannot see energy with our eyes, but we can sense and feel it. It has many forms (kinetic, gravitational, chemical, elastic, nuclear, electrical and radical). In science, we can measure energy in various units, such as joules, calories, kilowatt-hours, electron volts, quads and more. 

How Many Types of Energy?

In physic, energy is the allotment for doing work. Energy has many forms. The popular ones are potential, kinetic, thermal, chemical, electrical, nuclear, and more. Every form of energy is related to movement. For example, any item has kinetic energy when it is in motion. Humans cannot make, build or produce energy. However, they can transform from one form into another. The transformation is known as energy conservation. This conservation means energy can shift from one type to a different one. Below is the table of types of energy:

What is Heat Energy?

Heat is one of the energy types. It transferred intensity from one object to another because of the temperature differences. The impact of this transfer is the escalation temperature on the cold object and the lessening on the hot one. Hence, heat is the energy flow from a warm matter to a colder one. The source of heat is everywhere; even our body has it. Based on the Science Learning Hub of New Zealand, every object has heat energy. The movement of some minuscule particles, such as molecules or ions (in the form of liquid, solid or gases), results in heat. The warmth is transferable. For example, when we put ice cubes into a hot cup of tea, the ice will melt because the heat from the tea is transferred to the ice cubes. This transfer will also affect the hot tea as it becomes warm or even cold because of the low temperature of the ice cubes.

How Many Sources of Heat Energy?

Heat energy can be the fuel of a work. It is one of the essential types of energy for daily human life. We use it for cooking, ironing, heating food, and drying hair. There are plenty of sources of high-temperature energy:

• Sun: The bright sun is the largest source of energy for all organisms on Earth. It keeps life on this planet thriving for millions of years.
• Earth: The heat energy from the Earth is known as geothermal energy. We can find it in the spring or underground rocks.
• Air: The air consists of heat pumps for commercial and residential purposes.
• Burning Fuels: Burning fuels have a substance which could release heat energy if getting burned. Some examples of this source are wood, kerosene, diesel, coal, charcoal, oil, and more.
• Electricity: We can transfer the electrical energy to be heated with a device, such as a rice cooker, iron, or hair dryer.          

How is Heat Transmitted?

When an object's temperature rises, the particle inside will gain more energy. The excess can be transferred to other particles with lower temperatures. In the case of fast-moving particles bumping into slow-moving ones, it will send the power. This transaction will make the pace of slow particles become faster. The process will keep repeating until reaching the thermal equilibrium. When a solid object receives heat sufficiently, there will be an increase of energy in the particle. It will erase the bond that ties the elements. Hence, a solid object (ice cubes) can transform into liquid (water), and the liquid (water) can transform into a gas (evaporate).

1. Convection: Convection is the heat transfer process because of the movement of the particles in the object. It usually occurs in liquid or gas elements. The warm air is less solid than cold air, causing the warm air moves up and the cool air to replace them. The cold air turns warm, and the same cycle happens again.
2. Conduction: Conduction is a heat transfer from one solid object to another. The transmission can happen when two pieces of stuff touch each other. An example of conduction is when putting a pan on top of a burning stove. The heat from the stove will affect the pan and make it hot.
3. Radiations: Radiation is a heat transmission process in which the temperature goes through a place with no molecules. It is an example of electromagnetic energy. We can feel the heat without direct contact with the object. An example of radiation is when we feel the sun or campfire warm.
