Question

What is the approximate temperature of vinegar in room temperature? When in contact with baking soda?

Answer 1

25ºC is room temperature.

Answer 2

Would the temperature of vinegar be 25 also? What about when in contact with baking soda?

Answer 3

i think 25ºC is the assumed room temperature of vinegar and when its reacting with the baking soda, the temperature will increase as its a neutralisation, its exothermic
but when there's a release of CO2, it cools down so you may notice a rise and fall of temperature
