record the mass accurately measure and observe the mass and the volume of the different objects use appropriate apparatus and methods to measure volume and mass and ...

A planet’s mass and volume are easy to determine. Because planets are nearly spheres, we can calculate volume from our knowledge of a planet’s radius, which we determine by measuring both the planet’s ...

What is the purpose of prescribed practical P4? To investigate experimentally the relationship between the mass and volume of liquids and regular solids, and analyse and interpret the data gathered.
