What temperature will hot tea become if it is left for 1 hour?

It's impossible to give you a precise temperature without more information! Here's why:

* Starting Temperature: The hotter the tea starts, the longer it will take to cool. A boiling tea will cool much slower than tea that's just been warmed.

* Ambient Temperature: The temperature of the surrounding air or environment plays a huge role. Tea will cool faster in a cold room than in a warm one.

* Container: A thin ceramic mug will lose heat faster than a double-walled thermos.

* Other Factors: Things like air currents, the type of lid on the cup, and even the size of the cup can influence cooling.

General Idea:

Hot tea will generally cool to close to room temperature within an hour, but it's a gradual process. It won't be lukewarm right away.

To get a more accurate answer, you'd need to:

* Know the starting temperature of the tea.

* Know the temperature of the surrounding environment.

* Consider the type of container holding the tea.
