Question 25 Dylan carried out the following procedure: Step 1 Take a clean, dry jar, and place a lid tightly on it. Step 2 Allow it to stand for 10 minutes in a shaded spot, and observe. Step 3 Put it in a freezer for at least an hour. Step 4 Remove the jar from the freezer and observe. Dylan found that after Step 2 the jar was clean and dry on the inside, but after Step 4, there were ice crystals on the inside of the jar. The most likely explanation for this is that A. the warm jar was placed on some ice cubes that melted. B. cold air from the freezer entered the jar. C. cold air can hold more water vapour than hot air. D. hot air can hold more water vapour than cold air.

Concept explainers

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.
