Is melting a chemical change physical change absorption or displacement?
Melting is a physical change.
Why does absorption of heat cause chemical change?
By itself it doesn't.
What happens to energy during a chemical change?
when a chemical change occurs, chemical bonds are broken up
What is energy in a chemical change?
You think probable to chemical energy.
When does chemical energy change into nuclear energy?
This does not happen, they are quite differenwell sometime chemical change into nuclear by going to thermal energy
What observations does not indicate that a chemical change has occurred a. change of state b. formation of a precipitate c. absorption of energy d. release of a gas?
acually the answer depends on the nature of chemical reaction under consideration and depending on the reaction, there are two possible answers: a change of state and absorption of energy.
How could you tell if a chemical reaction was happening?
realease or absorption of energy product of a gas formation of a precipitate change in color
What is proof of a chemical change?
A release of gas; a color change; release or absorption of energy and burning. Chemical changes are not easily reversed and sometimes may not be possible at all.
What does endithermic change mean?
Endothermic change is a chemical reaction that is accompanied by the absorption of heat, or it is an organism that generates heat to maintain its temperature. When a chemical reaction occurs, energy is transferred to, or from, the surroundings. There is often a temperature change. An example would be that of a bonfire which transfers heat energy to the surroundings.
What are some of the signs that a chemical change has occurred?
A sign of a chemical change is the release or absorption of energy in the form of light, heat, or sound. Also, the formation of gas or a solid that isn't the result of a change in state.
Is light absorbed in physical change?
Heat absorption is a physical change. It can cause a change in state and/or a temperature increase, but the matter that is absorbing the heat does not change. It retains all of its physical and chemical properties that it had before absorbing the heat.
Is energy involved in all changes?
yes all changes involve exchange in energy
Is melting a chemical change physical change absorption or displacement?
Melting is a physical change.
Why does absorption of heat cause chemical change?
By itself it doesn't.
Energy can be taken in only during a chemical reaction?
No, chemical reactions are not the only reactions that may involve absorption of energy. A physical change like heating water to vapor is also endothermic.
The function described as consumption and the absorption of energy through photosynthesis is called?
The function described as the consumption and the absorption of energy through photosynthesis is a physico-chemical process.
What kind of energy does chemical energy change to?
Chemical energy can change into just about any other type of energy.
