liquid plastic is frozen in a physical change that increases its volume. what can be known about the plastic after the change?\no its mass will increase.\no its density will increase.\no its mass will remain the same.\no its density will remain the same.
Answer
Explanation:
Step1: Recall mass - conservation principle
In a physical change, mass is conserved. So, the mass of the plastic does not change when it freezes.
Step2: Analyze density formula
Density $\rho=\frac{m}{V}$. Since $m$ is constant and $V$ (volume) increases during freezing, $\rho$ (density) will decrease.
Answer:
Its mass will remain the same.
