Question

sonia wanted to make ice pops. she filled cups with 150 ml of juice and put them in the freezer. how will freezing the juice affect its mass?
a freezing the juice will not change its mass.
b freezing the juice will decrease its mass.
c freezing the juice will first increase and then decrease its mass.
d none of the above

Explanation:

Mass is a measure of the amount of matter in an object. When juice freezes, it changes state from liquid to solid, but the amount of matter (the number of particles) remains the same. So the mass should not change. Option a is correct as freezing is a physical change that doesn't add or remove matter, thus mass stays constant. Option b is wrong because mass doesn't decrease in freezing (no matter is lost). Option c is wrong as there's no such change in mass during freezing.

Answer:

a. Freezing the juice will not change its mass.
