What is a chemical property?
the ability of a substance to REACT with other substances in a certain way.
characteristics of matter than you can observe directly or measure with a tool
Which statement is true?
The answer may be hard to understand - but read each one and you will see the ones that are wrong / false. You need to select the one that is TRUE.
Most chemical changes CAN be reversed.
The ability to melt is a chemical property.
A chemical change increases the matter of a substance.
Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties.
Why might a glove stick to a sweater when you take them out of a clothes dryer?
Both items are dry.
The glove and the sweater have opposite charges.
An electric current flows between the glove and the sweater.
An electric current reduced the number of electrons in both items.
What happens when you flip on the switch for a light?
The electrical source turns on.
The circuit closes, and the electric current flows to the light.
The circuit opens, and electric current flows to the light.
Electric current is transferred from a different load to the light.
Which statement describes a difference between static electricity and electric current?
Only electric current involves energy.
Only electric current involves the movement of electrons.
Only static electricity involves sudden electric discharges.
Only static electricity involves negative and positive charges.
