The table below shows the mass and volume of four objects: Object | Mass (g) | Volume (cm³) -------|----------|------------- Aluminum figure | 230 | 85 Lead weight | 800 | 70 Steel block | 200 | 25 Wood puzzle | 400 | 500 (i) Which object is the heaviest? Your answer: The lead weight is the heaviest.

Answer: The heaviest object is determined by comparing the mass of each object. In the table, we see that the mass of the aluminum figure is 230g, the lead weight is 800g, the steel block is 200g, and the wood puzzle is 400g. Out of all these, the lead weight has the highest mass at 800g, making it the heaviest object listed in the table.

Extra: When comparing objects by weight, we are referring to the amount of matter that an object contains, which is measured by its mass. The terms "mass" and "weight" are often used interchangeably, but they have different meanings. Mass is a measure of the amount of matter in an object and does not change with the object's location. Weight, on the other hand, is the force exerted by gravity on an object's mass. Weight can change depending on where it is measured because the strength of gravity can vary slightly from place to place, such as from the Earth's surface to the Moon. However, in everyday contexts on Earth and in the table provided, we are considering mass as the indicator of how "heavy" an object is. The units provided (grams) indicate that mass is being measured, rather than weight which would be measured in newtons (N) if we were considering the gravitational force.
