Unit 6 Knewton Exam Questions With Verified Answers. According to KMT, at constant pressure and temperature, the frequency and force of molecule wall collisions are constant. So increasing the number of gaseous molecules will require a proportional increase in the container volume in order to yield a decrease in the number of collisions per unit area to make up for the increased frequency of collisions. What gas law is KMT explaining? - answerAvogadro's law The average kinetic energy of gas mol...

condensation of rain from water vapor - Answer melting ice cubes Melting ice cubes are an example of an endothermic process, because heat energy is taken from the surroundings when ice cubes melt. Burning sugar and a candle burning are both chemical reactions which give off heat energy, so they are both exothermic. When water vapor condenses, more energetic gas molecules become less energetic liquid molecules; the heat energy from the more energetic molecules in the gas phase is given off ...
