Is water condensing a reversible change?
Expert Answers info Evaporation is a reversible physical reaction.
The reverse process is water condensing from the atmosphere onto a surface.
Evaporation involves the change in state from liquid to gas..
Which processes are reversible?
In thermodynamics, a reversible process is a process whose direction can be returned to its original position by inducing infinitesimal changes to some property of the system via its surroundings. Throughout the entire reversible process, the system is in thermodynamic equilibrium with its surroundings.
What is the reverse of boiling?
Boiling is the phase change when a liquid becomes a gas. The opposite of that (a gas becoming a liquid) is condensing. … A similar process happens to form clouds (clouds are droplets of liquid, not gas).
Why is boiling water a physical change?
For example, mixing salt and pepper creates a new substance without changing the chemical makeup of either component. … Boiling waterBoiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O).
When you boil water is it a physical or chemical change?
Boiling waterBoiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.
Why is water boiling not a chemical reaction?
For example, a gas (water vapor) is given off when water boils. Recall that boiling is a physical change, not a chemical reaction. You can tell that it is a physical change because water vapor can condense to form liquid water. In a chemical change, a new substance must be produced.
How do you know if its a physical or chemical change?
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

Is butter a reversible change?
When butter melts, it goes from a solid state to a liquid state. That’s a physical change. It’s easily reversible if you return the butter to a cold place where it solidifies again. It would become a chemical change if you heated the butter to melt it and, in doing so, cooked some of the particles.
What is difference between reversible and irreversible change?
Reversible changes, like melting and dissolving, can be changed back again. Mixtures can be separated out by methods like filtering and evaporating. A change is called irreversible if it cannot be changed back again.
Is boiling a reversible process?
This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you cool this vapor down, it turns back to water. A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change.
What is reversible change give example?
Reversible changes A reversible change might change how a material looks or feels, but it doesn’t create new materials. Examples of reversible reactions include dissolving, evaporation, melting and freezing.
