Question

2. The relative density of a substance has the
same numerical value as its density in SI
units.
3. A substance with a relative density of less
than 1 is lighter than water.
4. The greater the mass of a body, the greater is
its volume.
5. The density of water is 1000 kg/m”.
6. Ice is lighter than water.
7. Weight is a force.​

Answer 1

Answer:

please solve my question

Answer 2

2. The relative density is the unit less quantity.   Hence, the given statement can be false.

3.If a substance has a relative density that is greater than 1, it will sink in water and if its relative density is less than 1, it will float in water.

4. False. An object's mass is independent of it's volume. The ratio of the mass to volume does change its density.

5.true.

6.ice is less dense than water.

7. gravity, w = mg.the weight is a force, its SI unit is the newton
