What is an electromagnet?
An electromagnet is a type of magnet where the magnetic field is produced by an electric current.
An electromagnet is a permanent magnet that does not require electricity.
An electromagnet is a type of magnet that only works in high temperatures.
An electromagnet is a magnet that can only attract non-metallic objects.
Which of these actions will cause a chemical change?
Burning a substance causes a chemical change.
Dissolving sugar in water.
Melting ice into water.
Mixing sand and salt.
What is the difference between a physical change and a chemical change?
A physical change alters the form of a substance without changing its identity, while a chemical change results in the formation of new substances.
A physical change involves the creation of new substances, while a chemical change does not affect the substance's identity.
Both physical and chemical changes result in new substances being formed.
A physical change is reversible, while a chemical change is always irreversible.
What is a chemical change?
A process where substances combine or break apart to form new substances.
