Water ~ 295.7353 milliliters (1 ¼ cups) Vegetable/Canola oil ~ 70.9765 milliliters (1/3 cup)
3
3 eggs ~ Heterogeneous mixture 295.7535 ml water (H 2 O) ~ Pure substance (compound) 70.9765 ml vegetable oil ~ Homogeneous mixture Cake mix ~ Homogeneous mixture Eggs Cake mix

Eggs ~ liquid: The molecules move around and take the shape of their container. Water (H 2 O) ~ liquid: The molecules move around and take the shape of their container. Vegetable oil ~ liquid: The molecules move around and take the shape of their container. Cake mix ~ solid: The molecules slightly move.
5
Chemical: Baking the cake (changes from a liquid to a solid). Physical: Mixing the batter with the water, oil and eggs. Adding decoration to the cake is also a physical change. So is cutting the fondant. LiquidSolid Cutting the fondant
6
Conduction: The transfer of heat through matter by communication of kinetic energy from particle to particle. The metal pan acted as a conductor of the heat. The heat transferred from the pan to the cake. Kinetic Theory: The kinetic theory states that molecules are always in motion. When the batter was mixed, the molecules where moving more than after it was baked because it went from a liquid to a solid.
7
After baking, the properties of our cake had turned from a liquid to a solid. The cake turned into a homogeneous mixture and the ingredients can no longer be separated.
