A physical change is causing a change in phase from liquid to gas. A chemical change has caused the liquids to undergo combustion and gas is escaping. A physical change is causing the solution to exhibit different properties than the original substances. A chemical change has resulted in the production of a new substance, which is being given off as a gas. Suppose you put popcorn kernels into an airtight popcorn popper and measure the mass of the popper and measure the mass of the popper with the kernels. After the popcorn has popped, what would you expect to find regarding the mass of the popper and the popcorn? The mass after popping will be less than the original mass because the popped corn is less dense than the kernels. The mass after popping will be equal to the original mass because the airtight container did not allow any materials to enter or leave the popper. The mass after popping will be greater than the original mass because the volume of the popped corn is greater than that of the kernels. The mass after popping will not be able to be determined accurately because of the steam that is released from the kernels during the popping.
