David is a physicist. He teaches school children how matters and energy work. One day he was teaching them about two particles of matter, particle A and particle B. Particle A moves faster, but particle B moves slower. He was showing the children about different characteristics of moving particles. Which particle would have less kinetic energy, particle A or particle B?
Ans: particle B

Jeremy is studying the periodic table in preparation for a chemistry test next week. Today he is focusing on the elements that all belong to the alkali metals group. He is especially focused on learning about lithium, which is at the top of the group, and cesium, which is at the bottom of the alkali metals group. Which element has a larger ionization energy?
Ans: lithium

Due to an increase in the number of factories releasing carbon dioxide the concentration of it has increased. Recent reports show a correlation between increasing levels of carbon dioxide and the average global temperature increasing. Given the average temperature increases even more, will the concentration of carbon dioxide have increased or decreased?
Ans: increased

Two identical chemical compounds are both in beakers on top of burners in a laboratory. Beaker A is sitting on top of a burner that is set to a low temperature, and Beaker X is on a burner with a high temperature. Ken, the scientist studying these compounds, is closely monitoring the chemicals to see what type of changes occur. Which beaker's particles have more energy?
Ans: Beaker X
