a: water heater ~
b: a big pressure cooker
What:
"Your water heater is like a big pressure cooker. Water is heated in a steel tank. Steam is produced which increases the pressure in the tank. On the top of your water heater is a pressure release valve. Should your water heater thermostat malfunction and the temperature build up to a dangerous level, this valve will open and let the pressure escape."
