Hot, Cool, or Cold: Choosing Temperature Words
Ravi is studying in Japan in August. Today the temperature is 36°C and the sun is very strong. In his room the air conditioner is set to 26°C, so the room feels pleasant. He takes a bottle of tea from the refrigerator; the tea is very cold. His Japanese friend asks him three questions: about the weather today, about his room, and about the tea. Ravi knows four words: あつい, すずしい, さむい, and つめたい. He thinks さむい might be correct for the tea because English 'cold' covers both weather and drinks. He also wonders whether あつい can describe the tea, and whether すずしい is only for weather. He wants to answer naturally, not just grammatically.
1. Choose the best word for (a) today's weather, (b) Ravi's room, and (c) the tea. Justify each by what the word describes, not by translating English 'cold' or 'hot'.

(a) あつい: it describes high temperature in air or weather, and 36°C with strong sun is exactly that. (b) すずしい: it describes pleasantly cool air, such as a room at 26°C with the air conditioner on. (c) つめたい: it describes something cold to the touch, including drinks and food taken from a refrigerator.
The key is noun class. あつい and さむい cover weather and air, and さむい also covers a person feeling cold. つめたい covers objects and liquids. English 'cold' spans both さむい and つめたい, so a direct translation cannot decide the answer; the noun being described does.
2. Ravi says 「この おちゃは さむいです」. Explain why a Japanese listener finds this odd, and what the listener might imagine.

さむい describes weather or air that is uncomfortably cold, or a person who feels cold. A drink is an object, so the natural word is つめたい. Saying 「おちゃは さむい」 makes the tea sound like a person or a place feeling cold, which is unnatural.
The listener would still understand the intended meaning but might briefly picture cold weather or a cold room, because さむい activates that frame. This is a collocation problem rather than a grammar problem: the sentence is well formed, but the word choice does not match the noun. Ravi should say 「この おちゃは つめたいです」.
3. If the tea were hot, could Ravi use あつい? Could he use すずしい for the tea? Explain the boundaries between these words.
Read the worked answer
For hot tea, あつい is fine: 「あつい おちゃ」 is natural because あつい can describe objects as well as weather and people. For cold tea, つめたい is the natural choice. すずしい does not work for a drink: it describes air, weather, or a place that feels pleasantly cool, not an object's temperature.
The boundary is therefore not simply 'high temperature' versus 'low temperature'. あつい and つめたい can describe objects; あつい, さむい, and すずしい describe weather and air; さむい also describes a person's sensation. Ravi should ask what kind of thing he is describing before choosing the adjective.
