冷ます vs 冷やす

　　　　　
みなさん、こんにちは！

The typhoon #11 has been gone, it was not that bad than we have heard which was good.

Today I have a quiz for you.
What are the differences between ｢冷(さ)ます｣ and ｢冷(ひ)やす｣?

The followings are from the online dictionary which I use quite a lot :

· 冷ます
cool down // damp down（熱意を）
【他動詞(transitive verb)】
1. chill
2. cool

· 冷やす
cool down
【他動詞(transitive verb)】
1. chill
2. cool
3. refrigerate（食料・飲料などを保存するために＝ in order to preserve beverages and foods）

Seems like English translations are almost the same.
I think this is one of the difficult parts that you find right words when you write/speak.
