What part of a burning candle takes place and physical change?
The melting of the wax is a physical change. The burning the of wick is the chemical change
How do you know when a physical change is taking place?
The best way to know when a physical change is taking place is to observe. There will be a visible change in physical changes.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
Are clouds a physical or chemical change?
Physical because no reaction is taking place.
How can you tell that the burning of a candle causes both physical and chemical change?
By observation: 1. A flame shows that heat is being generated, indicating a chemical change taking place. 2. A physical change would be the solid wax changing to liquid under the flame.
When candle is broken in half does this indicate that only a physical change is taking place?
Yes.That's a physical change only.
Exameple of a physical change and a chemical change?
A physical change is a change that can be undone. A chemical change cannot be undone. An example of this would be dissolving salt in water. This is a physical change because if you let the water in the container evaporate the salt will be left behind. A chemical change would be like burning a piece of wood since you cannot undo the change taking place to the wood.
When a log burns in a fire is a physical change taking place?

Because no chemical reaction is taking place. It is the same substance, just in a different state of matter.
Mixing magnesium and the product of burning magnesium with hydrochloric acid is it a physical or chemical change?
Mixing magnesium and the product of burning magnesium with hydrochloric acid would lead to a chemical change. The reaction between magnesium oxide (product of burning magnesium) and hydrochloric acid would produce magnesium chloride and water, showing a chemical reaction taking place due to the formation of new substances with different properties.
Is it a physical change when a candle changes size by burning?
Oh, dude, yes, it's totally a physical change when a candle burns and changes size. The wax is melting and then solidifying again as it cools down, so it's like a hot and cold dance party for the molecules. It's not like the candle magically grows or shrinks, it's just physics doing its thing.
