Each division of a laboratory thermometer with 50 divisions between 0°C and 100°C measures 2°C. This is calculated by dividing the total temperature range (100°C – 0°C) by the number of divisions.

A laboratory thermometer is not used to measure body temperature because it has a wide range and low sensitivity, which makes it unsuitable for accurately measuring the narrow temperature range of the human body.
The latent heat of vaporization is the amount of heat required to convert liquid water into steam at its boiling point without changing its temperature. It is about 2260 kJ/kg for water.
The latent heat of fusion is the amount of heat energy required to change water from solid ice to liquid water at its melting point, without changing its temperature. It is 334 kJ/kg.
Temperature affects the state of water by influencing its phase transitions. Increasing temperature can cause ice to melt or water to evaporate, while decreasing temperature can lead to freezing or condensation of water vapor.
