Ko tētahi o ngā hanga matū e toru. Ko ētahi haurehu e mōhio whānuitia ana ko te hāora me te hauhā. He ngoikore te pipiri o ngā ngota o tētahi haurehu, he māhorahora, he matapōkere te nukunuku. Ka whakakī te haurehu i te ipu e pupuri ana i taua haurehu. Kei te takiwā o te 30 tiriona ngā ngota kei roto i te hau takiwā e pupurihia ana i tētahi ipu he rite ki te pouaka māti te rahi. E pātata ana ki te 1,800km/h te tere o te nukunuku o ēnei ngota. Mā te whakamātao i te haurehu ka pōturi te nukunuku o ngā ngota, ka tōtā, arā, ka huri hei wē.
One of the three states of matter. Common gases include oxygen and carbon dioxide. The atoms of a gas are not strongly held together, and they move freely and randomly. A gas fills the container that is holding it. There are about 30 trillion atoms in the air in a container the size of a match-box. The atoms are moving at about 1,800km/h. By cooling a gas the movement of the atoms is slowed, it condenses and forms into a liquid.
