Atoms, molecules, compounds and mixtures, although they may not seem it, are different. Atoms make up all of the above and elements. They are made an equal amount of protons and electrons. Molecules are made when two or more atoms connect chemically. Like molecules, compounds are made when two or more atoms connect chemically. Unlike molecules, the atoms need to be two or more different elements. Mixtures are made of two or more compounds or elements. Mixtures can look completely the same when mixed together (homogeneous) or can be made of separate, noticeable pieces (heterogeneous). Atoms, molecules, compounds and mixtures can be in different states. The three main states of matter are; solid (when the particles are compacted with little energy), liquid (when the particles are spread further apart and have more energy), and gas (when the particles are widely spaced and have lots of energy). When a solid becomes a liquid, it melts. When a liquid becomes a gas, it boils. When a gas becomes a liquid, it condensates. When a liquid becomes a solid, it freezes. When particles are heated they get more energy, spreading out.
Physical changes include the changes between a liquid, solid or gas. They also include the changes in size and shape. Physical changes easily get confused with chemical changes. Chemical changes …show more content…
This was met as each cupcake had a different, appropriate outcome. The hypothesis was that the increase of amount of baking powder would increase the size of the cupcakes. The results of the experiment supported this hypothesis, as the cupcakes with more baking powder were larger than the cupcakes without or with less baking powder. A different option for this experiment could be to change the quantity of the egg in the recipe. Changing the egg amount would affect many different aspects of a cupcake, including moisture, texture, structure, nutrition and
