a molecule having slightly negative and positive ends with regard to change
A change in the nucleotide base sequence of gene or DNA molecule is called a what?
this is called a mutation
Is a sugar cube ground up a chemical change?
If the temperature is below the decomposition temperature, then melting a physical change not chemical as the liquid sugar (or molten sugar) can be solidified again.
Is painting a door a physical or chemical change?
Physical change of the paint, not the door.
Liquid alcohol will change to vapor when its temperature reaches the what?
Liquid alcohol will change to vapor when its temperature reaches its boiling temperature. When alcohol reaches its boiling temperature, each molecule of alcohol has enough energy to separate from each other, so each molecule can move freely. The boiling point of liquid alcohol is 351K or 78C
When is a phase change and when is it a sign of a chemical change?
After a physical change the molecule remain intact.After a chemical change the molecule is modified.
What is a chemical change but not a physical change?
Chemical change: the structure of the molecule is modified. Physical change: the structure of the molecule is not modified.
What is the diference between a physical change and a chemical change?
Chemical change: the structure of the molecule is chenged. Physical change: the structure of the molecule is not changed.
Why is boiling or melting a physical change and not a chemical change?
because you dont change the molecule. H2O IS THE SAME MOLECULE as water, ice or steam

What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
Why does a chemical change differ from a physical change?
A chemical transformation change the structure of the molecule but a physical transformation not.
