Explanation:
The phase of matter can be changed by:
a) increasing temperature
b) decreasing mass
c) increasing volume
d) all of the above
Answer: A
Explanation: Mass and volume is the amount, amount doesn’t make the phase of a matter change.

What is most likely to occur during a chemical reaction?
a Molecules of the original substance are lost. b New atoms are created. c The original substance maintains its properties. d Mass is conserved.
During a chemical reaction, the most likely occurring is mass conservation. According to law of conservation of mass, total mass in a reaction is conserved.
What is law of conservation of mass?According to the law of conservation of mass, the total mass in a chemical reaction or in a physical change is conserved. Simply, mass is neither created nor destroyed.
When a chemical reaction takes place, no new atoms are created and the properties of the reactant species cannot be maintained after reaction.
Molecules of any reactant is not lost during a reaction. The total mass in the reactant side of a balanced reaction will be equal to the total mass in product side.
Therefore, the mass conservation is likely to occur during a chemical reaction. Thus, option d is correct.
