In the previous lesson, you learned about the different forms of energy. Can you still recall them? answer the activity below.
Activity 1: What Am I?

Directions: Identify the forms of energy used in the following activities / appliances. Write your answer
inside the box.

Drying clothes
Cooking of food
Lighted candle
Lighted lamp
Sewing of clothes
The world population relies heavily on energy of all forms. Energy appears in different forms: heat, light,
sound, and electricity. It can flow from one place to another and can be transformed from one form to another.
Every day of our life, you experience multiple energy transformations. For everything, energy transformation
is always involved.

Hope it helps buddy (☞ﾟ∀ﾟ)☞

Answer from: homersoncanceranguiu

answer:

1.A matchstick has a lot of chemical energy stored in it. When the match is struck, it burns and the chemical energy in it produces heat energy and light energy. Candles also possess a lot of chemical energy.2.The guitar uses electrical energy. The guitar produces sound energy when the strings are plucked3.electrical energy answer: Face the front of your pinwheel and blow directly at it. Imagine that the pinwheel is a wind turbine and when it spins this direction it is turning the energy of the wind into electrical energy.4.This is because the neutrality of polarity can be changed by electric field in this case. When you create - charge in the comb and you expose the pieces of paper to the electric field created by the charge, you will polarise them so that the part closer to the comb will be + and the other will be -5. it is common knowlegde that animals out in the wild usually run or fly away if a human walks up to them , from the experience and from the text , young readers can draw this conclusionHOPE IT HELPS

answer:

Energy transformations

Energy transformationsEnergy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation.Energy must obey the laws of thermodynamics.Thermodynamics is the study of how energy changes from one type to another. The laws of thermodynamics apply to energy and energy conversions.The first law of thermodynamics:main articleEnergy cannot be created or destroyed (which is called the conservation of energy); however, it can be transformed from one type into another. In fact, every useful process transforms energy from one form to another. There are many different forms or types of energy. Some examples of everyday energy transformations are:(PICTURE)

The second law of thermodynamics:main articleSome forms of energy are more useful than others. Using energy always makes it less useful, even though no energy is actually destroyed.Kinetic energy and electricity are the most useful forms. These are "high-quality" because they can be transformed almost completely into any other type of energy. Electricity, for example, can be easily used to generate heat (thermal energy) or light (radiant energy), break chemical bonds (chemical energy), move objects (kinetic energy), or lift objects (gravitational potential energy).The least useful form of energy is low-temperature thermal energy. It can still be converted back to a higher-quality form, but useful energy is always lost in this process. Converting energy to a less-useful form and then trying to work backwards never gets 100% of the useful energy back.For example, when a car runs, the engine will become hot (thermal energy). The warmth of the engine does nothing to help the car move or go faster. This wasted energy is an unavoidable by-product of converting the car's fuel (chemical energy) into movement ("high-quality" kinetic energy), however it can potentially be used for heating the cabin of the car to slightly increase overall energy efficiency. It is a challenge for all forms of power generation to minimize wasted energy and be as efficient as possible.PhET: Energy Forms and ChangesThe University of Colorado has graciously allowed us to use the following PhET simulation. Click to run an interactive simulation to explore transformations between types of energy. Specifically, this simulation deals with conversions between forms of mechanical, electrical, chemical, and light energy.
