true or false- if you only want a small volume of hot water, you should place the immersion heater near the bottom of the hot water tank?

• physics******************** -

Between room temperatures and boiling point, water is lighter when hot than cold. So cold water rises to the top when it gets hot.

What would be your choice to heat up a "small" amount of water?
