A student places a thermometer in hot water during a lab and the column of fluid inside the thermometer rises to 90 ° Celsius. What causes the change in the thermometers' readings?
A) Entropy causes fluid in the thermometer to crystalize and expand.
B) The hot water acts as a catalyst causing a chemical reaction in the thermometer.
C) Radiation from the water causes fluid in the thermometer's bulb to push the fluid in the column higher .
D) The heat of the water causes molecules in the thermometer's fluid to move faster, spread apart, and rise in the thermometer's column.

Answer

D) The heat of the water causes molecules in the thermometer's fluid to move faster, spread apart, and rise in the thermometer's column.

When fluids are heated they increase in size. This is called expansion. when the thermometer is placed inside the hot water, the water heats up the bulb that in turn conducts the heat to the liquid inside the thermometer.

The heat causes the motion of the molecules of the liquid to increase. Thus the molecules spread out occupying more space. This makes the thermometer's column to increase.
