Below are several statements. Each statement can best be classified as either a law or a theory. Please select each statement that is best classified as a law. O When a gas rises in temperature, we beleve that it is due to increased motion of the molecules. O Gravity explains why planets remain in their orbits. O There is strong evidence to suggest that earthquakes are due to moving parts of the earth's crust that we call plates. a Force equals mass time a When we see several layers of rock, the lower layers are older. s acceleration. O With all other conditions remaining stable, we observe that as the pressure of a gas increases, the temperature also rises. Likewise, when the temperature rises, the pressure rises. O Kepler developed a set of rules to describe the motion of the planets. Based on the available data and our current understanding, it seems that the Universe began with a sudden expansion of space.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
