Option B
The molecules in thermometer spread apart
Explanation:
The mercury within the thermometer spread apart leading to an increase in temperature reading in the thermometer. The spreading apart of mercury molecules is caused by an increase in kinetic energy of molecules and with time the increase in kinetic energy decreases making the reading to stop increasing hence constant.
A tachometer measures, for example it measures the MPH(Miles Per Hour) in a car. So like it measures your speed, so you could be going 100 MPH.
I can conclude that the aluminum heats up faster then the water, since how they are made up is more different, each has a different compound to it, plus water is more denser<span />
