Question

Xavier boiled 19 grams of water. If all of the water changed into a gas, what would be the mass of the steam?

Answer 1

Answer:

19g

Explanation:

The mass of the steam produced in this phase change process will also be 19g. This is in compliance with the law of conservation of mass.

• It states that "mass is neither created nor destroyed in a the cause of reaction".
• The law suggests that mass is conserved.
• When steam is heated, it does not lose its mass.
• The mass of the steam is still the same as that of water.
