fiery

Compared meaning: having a high temperature or heat (adjective).

比较义项：温度高、带有热度（形容词）。

• hot

  The basic, everyday word for a high temperature; used freely for food, drinks, weather or objects, with no hint of how the heat got there.

  表示温度高的最基础、最常用的词，可以自由用于食物、饮品、天气或物体，不涉及这种热是怎么来的。

  Be careful, the plate straight from the oven is still very hot.

  小心，这个盘子刚从烤箱里拿出来，还很烫。

• thermal

  Describes things that relate to heat itself, such as heat-sensitive equipment or warmth-trapping clothing, rather than an object's own temperature being high.

  描述与热本身有关的东西，比如对热敏感的设备或保暖的衣物，而不是说某个物体本身的温度很高。

  The company sells thermal paper for old fax machines and cash registers.

  这家公司为老式传真机和收银机出售热敏纸。

• fiery 本词

  Emphasizes intense, blazing heat, almost like fire itself; stronger and more vivid than hot, and rarely used for ordinary warm food or drinks.

  强调像火一样猛烈、炽热的高温，语气比 hot 更强烈、更生动，很少用来形容普通的温热食物或饮品。

  Sparks flew from the fiery furnace as the workers stoked the coals.

  工人们添煤的时候，炽热的炉子里火星四溅。

• heated

  Means warmed up by an outside process or device, such as a seat or pool, implying the heat was added rather than natural or inherent.

  指通过外部设备或过程被加热，比如座椅或泳池，暗示这种热是后来添加上去的，而不是天然或本身固有的。

  The heated seats kept us warm during the long drive through the snow.

  在穿越雪地的长途车程中，加热座椅让我们保持温暖。

Hot, thermal, fiery, and heated relate to heat. Hot is the everyday word for high temperature. Thermal relates to heat itself, like heat-sensing gear. Fiery means intense, blazing heat. Heated means warmed by an outside process. Their temper and argument senses are not compared here.

这四个词都与「热」有关，但用法不同：hot 是最基础、最常用的说法，可以自由修饰食物、天气或物体；fiery 强调像火一样猛烈灼热，语气比 hot 更强；heated 强调经过外部加热才变热，而不是本身固有的高温；thermal 强调「与热有关、用来保温」，很少直接说某物本身「是 thermal 的」来表示烫。这里不比较 fiery 的「脾气火爆的」义和 heated 的「（争论、情绪）激烈的」义。

Compared meaning: showing strong feeling or enthusiasm (adjective).

比较义项：情绪强烈、充满热情（adj.）。

  他始终坚信所有工人都应享有平等权利。

Passionate, fiery, impassioned, and fervent all show strong feeling, but the tone differs. Passionate is the most general, neutral word. Impassioned is formal, mainly for speeches. Fiery often suggests anger. Fervent stresses steady devotion or belief, not heat. Fiery's burning sense is not compared here.

这几个词都可以形容人或言语中强烈的情绪或热情，但语气和搭配不同：passionate 最通用中性；impassioned 偏书面，几乎只用于演讲、恳求等场合；fiery 常带愤怒、急躁的负面色彩；fervent 强调持久的忠诚和信念，而非情绪的炽热。这里不比较 fiery 的字面义“燃烧的”或“辛辣的（食物）”。

两个词都能形容强烈的情绪，但heated多用来形容争论、讨论等场面的激烈程度，而fiery多用来形容人的脾气容易发怒。fiery语气更强、更口语化，常与temper搭配；heated常与argument、debate等词搭配。
