Question
Explain why, when you boil water in a pan, the water boils much faster when the pan has a lid on it than when it does not.
Step 1
This is represented by the equation: \[ Q = mc\Delta T \] where \(Q\) is the heat energy, \(m\) is the mass of the water, \(c\) is the specific heat capacity of water, and \(\Delta T\) is the change in temperature. Show more…

Why does placing a lid over a pot of water on a stove shorten the time it takes for the water to come to a boil, whereas, after the water is boiling, the use of a lid only slightly shortens the cooking time?
Explain why? It takes longer to boil a pan of water than to heat a pan of water to 50 °C.
