Explain why dissolving is a physical change?
All physical changes are reversible because the molecules do not undergo change in any chemical reaction even in in the change in the state of matter. NaCl is a salt compound and each molecules gets easily dissolved in water and the salt recovered by evaporation of water.
What substance takes part in a chemical reaction easily?
8 letters
Cooking a chemical or physical change?
Both of those processes are parts of cooking. It depends on what you're doing. If you're melting or freezing its a physical change. If you're changing it into another substance then its chemical. A chemical change is when a substance is changed into another entirely different substance. This happens when an event occurs that changes the composition of the substance. Examples of chemical changes are color changes, absorbing energy, releasing energy, odor changes, producing gases, producing solids, and can't be easily reversed. A physical change is when there is a change is physical properties. This happens when an event occurs that doesn't change their chemical. Examples of physical changes are changes in the texture, shape, size, color, odor, volume, mass, weight, and density.
Why do you think the sublimation of dry ice and expansion of gases are not chemical reactions?
Because they are changes of state - physical changes - VERY easily reversed.
Explain why changes of state are considered physical transitions and not chemical processes?
This is because when a substance, such as water, is changed to a solid (ice) it keeps its same, original properties! A chemical change involves changing the substance into a completely new substance. Water, on the other hand, can go from a solid, to a liquid, to a gas without changing its properties, only its state!
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Explain why flammability and combustibility are chemical properties?
"A chemical property is the property of a substance that describes it's ability to undergo changes to its composition to produce one ore more NEW substance." - Nelson Science Peerspectives Textbook If you decide to toss your jeans into the fire they will burn causing a new substance we commonly know as ashes. So this means that the jeans had a chemical property, combustibility or flammability, that changed its compostion to produce a new substance. Making the properties, combustibility and flammability, both chemical properties.
Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
is water freezing into ice a chemical change?
No , it is not a chemical change because chemical changes are irreversible i.e. original substance cannot be recovered but in this change we can easily melt the ice and back to its normal state.
Which state of matter undergoes changes in volum most easily?
Gases undergo changes in volume very easily.solid

Is ability to freeze a chemical property of matter?
No, changes in state are classed as physical changes as no new substance is made amd the process is easily reversed.

Does matter undergo changes?
it undergoes change, cause these changes may be temporary and easily reversible or may permanent and very difficult to reverse.
What is a description of a substance that easily changes to a gas at room temperature?
Volatile
