Question

Match the following vocabulary terms to their definitions.1. the mass of a substance per unit volume density. 2. a proposed explanation for a scientific problem matter.3. standard metric unit of length control. 4. standard metric unit of mass meter. 5. anything that has mass and occupies space hypothesis. 6. a quantity in an experiment that remains un-changed or constant kilogram.

Answer 1

Explanation:

1. The mass of a substance per unit volume: Density

Higher density means the atoms are closely packed.

2. a proposed explanation for a scientific problem: Hypothesis

Before a problem is solved with an experimental or theoretical proof a hypothesis is given which is a probable solution for the problem. This hypothesis might be proved wrong at a later stage but it still works as a starting point to find a solution.

3. standard metric unit of length : Meter

The standard unit to measure the length.

4. standard metric unit of mass: Kilogram

The standard unit to measure the mass.

5. anything that has mass and occupies space: Matter

6. a quantity in an experiment that remains un-changed or constant: Control
