what do scientists use to measure the point when a liquid turns to solid

Scientists typically use a device called a thermometer to measure the temperature at which a liquid turns into a solid. This temperature is known as the freezing point or melting point of the substance.

Scientists use a device called a thermometer to measure the point when a liquid turns to a solid. However, it is important to note that a thermometer measures the temperature at which the phase change occurs, rather than directly measuring the physical change of the substance. The specific temperature at which a liquid turns into a solid is known as the freezing point or melting point of the substance being studied.
