Types of changes the hydrogen undergoes in a physical change?
Hydrogen gas become a liquid at very low temperature; and after we can obtain solid hydrogen.
Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
What is a physical change that takes place when oxygen and hydrogen are combined to form H2O?
When oxygen and hydrogen combine to form water there is a chemical change, not a physical change. That may be followed by a physical change, depending on the conditions when the chemical change occurs. You may, for example begin with water vapor and, if the temperature is low enough, it will condense (a physical change) to liquid water.
Is the change from a solid to a liquid a physical change?
Sure, change from solid to liquid is a physical change
Can water be separated into hydrogen and oxygen by boil physical change or chemical change?
Water cannot be separated into hydrogen and oxygen by boiling. Boiling is a physical change which means the molecule doesn't change at all--liquid water and water vapor are both H2O. Water can be separated into hydrogen and oxygen using electricity, this would be a chemical change.
What kind of changes are melting and freezing?
Melting, freezing, boiling, evaporation are physical change
Is liquid evaporating a chemical or physical change?
physical change, its molecules are gaining energy and evaporating
How could you change hydrogen solid to hydrogen liquid?
Heat it.
If Hydrogen turns into liquid is physical or chemical change?
It will be a physical change, because you're only changing the state of the element. Although it's really hard to do it, you can still change it back by changing the temperature being applied to it.
Why when the liquid is heated does the temperature not always increase?
If the liquid is heated to its boiling point, at which point it undergoes a physical change called vaporization, its temperature will not increase until the physical change is complete. This is due to the heat energy being used to break intermolecular bonds, such as hydrogen bonds, so that the physical change can take place.
Is pouring liquid a chemical change or physical?
A physical change.
Is melting physical or a chemical change?
it is a physical changeIce melting is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).See the Related Questions for more information.physical change is anything changing from a solid to a liquid
