When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.

Explain the process of using fossil fuel as energy?
They are burned with oxygen to produce energy.
Which energy changes takes place when a pedling cyclist uses a generator to light his bicycle lamp?
There are 2 energy changes that take place in this action: Mechanical to Light Energy and Mechanical to Electrical Energy. To explain further, when a generator, which uses mechanical energy, is used in turn to light up the bicycle lamp, the light emitted is light energy. At the same time, when the generator lights up the bicycle lamp, the lamp is light up using electrical energy, so mechanical energy also transformed into electrical energy. ===============================> heat and light (in the light bulb)
Why using 2 manipulated variables in an experiment would not be wise explain?
Well, when something changes, you would not know which variable caused the change in the experiment.
Give an example of a sentence using the word explain?

What type of energy are you using when use a candle?
Candles make chemical energy because the fire makes chemical energy!
How can you explain the physical change of a burning candle using the big idea of energy?
Well it is simple when you think about it reallly. The wax melting from the heat of the flame is the physical change. It will turn turn into a liquid and then later solidify.
What does it mean to consecrate a candle?
Consecrating a candle typically involves a ritual or prayer to cleanse and sanctify the candle for a specific purpose, such as for use in meditation, prayer, or spiritual practices. It is a way to imbue the candle with positive energy and intent before using it.
