How is measuring the the mass of a solid different from measuring the mass of a liquid?

Measuring the mass of a solid involves using a balance or scale to directly weigh the object. The mass of a solid remains constant regardless of its shape or volume. Measuring the mass of a liquid involves using a container to hold the liquid and then weighing the container with the liquid inside. The mass of a liquid can vary based on its volume and the container it is held in due to the fluidity and ability to change shape.
