Final answer:

A remote bulb thermostat works by using the expansion and contraction of the metal inside the bulb to control the temperature.


Explanation:

In a remote bulb thermostat, the metal in the bulb expands and contracts with temperature changes. As the temperature increases, the metal within the bulb expands, causing a change in pressure on the actuator. This pressure change then repositions a valve on the thermostat, controlling the flowrate of a coolant.
