Why? a Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. b с d Question 1 а C The molecules in the gas change phases and cling to the sides of the container d Due to the increased kinetic energy which results in higher impacts to the walls The fewer impacts among the molecules result in fewer collisions to the walls If a chemical reaction releases heat, which of the following describes it? Steam or water vapor enters the container and increases the pressure Question 2 Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. b The reaction is endothermic and has a positive ΔH. The reaction is endothermic and has a negative ΔH. The reaction is exothermic and has a negative ΔH.
