Is a Bunsen flame hottest when the hole is open or close?
A Bunsen burner flame is hottest when the air valve hole is open.
What is the temperature of the Bunsen burner regulated by?
The temperature of a Bunsen burner is regulated by gas and airflow. The gas is controlled by a flow valve and the air is controlled by a screw mechanism on the collar. Different type of nozzles can control the flame's shape. The Bunsen burner was invented in 1855 by Robert Wilhelm Bunsen (1811-1899).
