Question

Erica and Jim are given a closed container of ice. They find the mass of the container and ice to be 28.0 grams. The container of ice is left on the lab table overnight. The next day, Erica and Jim observed the container. All of the ice had melted. They place the container back on the balance and found the mass to be

Answer 1

Explanation:

When they weighed the container that was left overnight and all the ice got melted. The weight will be less than before e.g. 28 grams

This is due to the fact that the density of water is more than that of ice.

The density of water = 1.00 g cm-3 at 0 °C

The density of ice = 0.92 g cm-3

Since, we know that

Density = mass/ volume

Thus, mass will be increased
