Scientists measure mass with a balance, such as a triple beam balance
So A is true
<span> If mass remains the same while the volume of a substance increases and the density of the substance will decrease or, volume decreases and density increase, 'cause density equals mass divided in volume, which means that volume and density are inversely proporcional</span>
Answer:
they change the state of matter
Explanation:
Physical properties can be observed or measured without changing the composition of matter
Chemical properties are only observed during a chemical reaction and thus changing the substance's chemical composition
