Frequancy Tables only use whole numbers while relative frequency tables use exact percentages or decimals.
You can change the density of something by altering its mass and volume. Increasing the mass while keeping the volume constant will increase the density, while increasing the volume while keeping the mass constant will decrease the density.
Yes, an object's density can be changed by altering its mass or volume. Increasing the mass while keeping the volume constant will increase the density, while decreasing the volume while keeping the mass constant will also increase density.
While in weightlessness, your bone density and muscle mass decrease as you don't use them. So, by doing several hours of exercise a day, you are using the muscles and bones, therefore, the bone density and muscle mass do not decrease as much as they would if they didn't exercise.
To change the density of an object, you can either change its mass or volume. Increasing mass while keeping volume constant will increase density, while increasing volume while keeping mass constant will decrease density. Density is calculated as mass divided by volume.

Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of another substance, usually water. Relative density is also known as specific gravity. The relationship between relative density and density is that relative density is a comparison of densities, while density is an absolute measure of mass per unit volume.
No, cotton has a density of 1.54-1.56 g/cm³ while iron has a density of 7.874 g/cm³
Copper has a density of 8.9 g/cm3 while iron has a density of 7.9 g/cm3. Therefore copper is denser than iron.
No, the density of petrol is lower than the density of water. Water has a density of 1 g/cm³, while the density of petrol is around 0.75-0.85 g/cm³.
If mass increases while volume stays the same, density increases. If volume increases while mass stays the same, density decreases. Density is calculated as mass divided by volume, so any change in mass or volume will affect the density of a substance.
Lead has a greater density than silver. Lead has a density of 11.34 g/cm3, while silver has a density of 10.49 g/cm3.
