A sealed container has 50 grams of water.If the water. is completely converted to steam, what will be the mass of the steam? a 55 grams b 50 grams c 45 grams d 60 grams

## Step 1<br />The problem involves the principle of conservation of mass in a closed system. This principle states that the mass of a closed system remains constant, regardless of the processes happening within it. In this case, the closed system is the sealed container.<br /><br />## Step 2<br />The problem states that the water in the container is completely converted to steam. This is a physical change, not a chemical one. The mass of the water does not change when it is converted to steam.<br /><br />## Step 3<br />Therefore, the mass of the steam produced will be the same as the mass of the water that was originally in the container.
