The exact temperature of a glass of water in degrees Celsius

Answer 1

The temperature of water in a glass if room temperature is 21 degrees Celsius if a glass is standing one in that room, because room temperature is commonly given as 20 to 22 degrees Celsius, however, if the air in the room goes through temperature variations,then a body of water will heat up or cool down,then the temperature of the water in the glass tends to average out those temperature variations.
