The length of the column of mercury in the room thermometer tube has increased. Did this increase the number of mercury molecules? Has the volume of each mercury molecule in the thermometer changed?
The distance between the mercury molecules has increased due to the increase in temperature. This led to an increase in the volume of mercury in the thermometer, so the thermometer rose. The volume of molecules (the distance between their constituent atoms) has not changed, as well as their number, since The thermometer is hermetically sealed and there is nowhere to come from and there is nowhere to evaporate.
