Why does "Hoo" produce cold air but "Haa" produces hot air?【译】为什么“呼”产生凉气而“哈”产生热气？【单词】Hoo 原型：hoo [huː] int. 呼!(表示激动；高兴；歧视；赞许等)【单词】Haa 语气词，“哈”
The human body doesn't feel absolute temperature, what you feel is how much heat is entering (hot) or leaving (cold) your body (That's why metals always feel a lot hotter or colder than their surrounding, high heat conductivity).【译】人体觉得不到绝对温度，你觉得到的是有多少热量进入（热）或离开（冷）你的身体（这便是为什么金属总是觉得比它们周围的东西热很多或冷冷很多，由于金属的热传导率高）。【单词】absolute ['ab-suh-loot]['æbsəluːt] adj. 绝对的；确实的；完备的【单词】temperature ['tem-per-uh-cher]['temprətʃə] n. 气温；体温；温度【单词】heat [heet][hiːt] n. 热度；热【单词】entering 原型：enter ['en-ter]['entə] v. 进入【单词】metals 原型：metal ['met-l]['metl] n. 金属；合金【单词】hotter 形容词比较级，更热的，原型：hot 【单词】surrounding 原型：surround [suh-'round][sə'raʊnd] vt. 包围；环抱 n. 环抱物【单词】conductivity [kon-duhk-'tiv-i-tee][ˌkɒndʌk'tɪvəti] n. [物]传导性；传导率
So in the case of your breath, the air comes out faster on the "Hoo" sound.【译】以是在你呼吸的情形下，呼声中空气出来的速率更快。【单词】breath [breth][breθ] n. 呼吸；气息
A faster flow of air will carry more heat away from your hand via convection.【译】更快的气流将通过对流带走更多的热量。【单词】flow [floh][fləʊ] n. 流动；流；流量【单词】carry ['kar-ee]['kæri] v. 携带；运送；带有；承载
【单词】via ['vahy-uh, 'vee-uh]['vaɪə] prep. 经由；通过【单词】convection [kuhn-'vek-shuhn][kən'vekʃn] n. (热的)对流
As someone else pointed out, it is the same reason a fan cools you down even though the air doesn't get any colder.【译】正如其他人指出的，这是同样的缘故原由，风扇会让你以为凉爽，只管空气并没有变得更冷。【词法】even though是“只管”的意思，为连词，勾引让步状语从句用于勾引让步状语从句。如：He went out even though it was raining. 只管不才雨，他还是出去了。【单词】fan [fan][fæn] n. 风扇；扇子；扇形物【单词】cools 原型：cool [kool][kuːl] vt. (使)变凉；(使)冷却；(使)镇静 vi. 变凉；镇静下来
The reason the "Hoo" sound produces a faster airflow than the "Haa" sound for the same effort has to do with the opening size in your throat.【译】“呼”的声音比“哈”的声音产生更快气流的缘故原由与你喉咙的开口大小有关。【单词】airflow ['air-floh]['eəfləʊ] n. 气流；空气的气流【单词】effort ['ef-ert]['efət] n. 努力；努力的成果【单词】throat [throht][θrəʊt] n. 嗓子；喉咙；颈部
If your lungs are pushing the same amount of air in both instances, the air will have to come out faster if the opening is smaller.【译】如果你的肺在这两种情形下所排出的空宇量相同，那么如果开口较小，空气排出的速率就必须更快。【单词】lungs 原型：lung [luhng][lʌŋ] n. 肺；呼吸器官【单词】pushing 原型：push [poosh][pʊʃ] v. 推；按；挤；逼迫【单词】instances 原型：instance ['in-stuhns]['ɪnstəns] n. 例子；场合；情形
Think of a garden hose when partially block the opening with your thumb, the water comes out faster!【译】想想花园里的水管，当你用拇指部分堵住一部分开口时，水出来的速率会更快！
【单词】hose [hohz][həʊz] n. 水管；橡皮软管【单词】partially ['pahr-shuh-lee]['pɑːʃəli] adv. 部分地；不公正地【单词】block [blok][blɒk] v. 壅塞【单词】thumb [thuhm][θʌm] n. 拇指
When you move your hand up to your mouth, the air hitting it comes directly from your exhale.【译】当你把手举到嘴边时，呼气时碰到它的是直接来自你的呼出的气。【单词】hitting 原型：hit [hit][hɪt] v. 打（击）；达到
【单词】directly [dih-'rekt-lee, dahy-][də'rektli] adv. 直接地；立即；恰好地；完备【单词】exhale [eks-'heyl, ek-'seyl][eks'heɪl] v. 呼气；散发
Further away, the air hitting your hand is a mix of your breath and the air between your mouth and hand - which is significantly cooler.【译】再远一点，打在你手上的则是你呼出的气与你嘴和手之间的空气的稠浊，这是明显更凉一些的。【单词】mix [miks][mɪks] n. 稠浊(物)；领悟【单词】significantly [sig-'nif-i-kuhnt][sɪɡ'nɪfɪkəntli] adv. 意味深长地；意义深远地；主要地；较大地【单词】cooler 原型：cool 形容词比较级，更风凉
The further you go the colder the jet will be because the heat from your breathe disperses and dilutes more.【译】间隔越远，喷气的温度就越低，由于你喷出气体的热量会扩散和稀释得更多。【单词】jet [jet][dʒet] n. 喷射【单词】breathe [breeth][briːð] vi. 呼吸【单词】disperses [dih-'spurs][dɪ'spɜːs] v. 分散；散开【单词】dilutes 原型：dilute [dih-'loot, dahy-][daɪ'luːt] vt. 稀释；冲淡
The slower haa flow, on the other hand doesnt mix as harshly with the air (it pushes it away more, mixes with it less).【译】另一方面，“哈”气时较慢的气流与空气的稠浊并不那么剧烈（它将空气推开得更多，与空气的稠浊更少）。【短语】on the other hand 另一方面；例句：On one hand I have to work; on the other hand I have many visitors to see. 一方面我必须事情; 另一方面我有许多来宾要照看。【单词】slower 原型：slow 形容词比较级 更慢的，更慢地【单词】harshly [hahrsh][hɑːʃli] adv. 粗糙地；粗暴地；刺耳地
This mode of flow preserves its temperature for longer than the hoo.【译】这种流动办法保持温度的韶光比“呼”气要长。【单词】mode [mohd][məʊd] n. 办法；模式；样式；风格【单词】preserves 原型：preserve [pri-'zurv][prɪ'zɜːv] v. 保护；保存；保持
Both this and the convection effect factor into the final "temperature" you're sensing.【译】它与热对流效应两个成分都会终极影响你对“温度”的觉得。【单词】factor ['fak-ter]['fæktə] n. 成分；因数；因子
