WebMatter is defined as anything that occupies space and has mass, and it is all around us. Solids and liquids are more obviously matter: We can see that they take up space, and their weight tells us that they have mass. Gases are also matter; if gases did not take up space, a balloon would stay collapsed rather than inflate when filled with gas. WebThe decrease in mass occurs because water has been removed during heating. The mass of water lost can be calculated as the difference between the mass of the sample before heating and the mass of the sample after heating. After substituting in the mass values from the table, we get 4.97 grams minus 2.74 grams, which equals 2.23 grams. …
