MECHANICS : PROPERTIES OF MATTER - Density
How would you increase the density of an object?
Increase its volume.
Increase its mass and keep volume constant.
Decrease its volume and keep mass constant.
Decrease its mass.
An object weighs 30 N in air and 10 N when submerged in water. What is the density of the object?
4000 kg/m³.
2000 kg/m³.
3000 kg/m³.
1000 kg/m³.
If the density of a material is 2 g/cm³, what is the density of this material in kg/m³?
2 kg/m³.
2000 kg/m³.
1000 kg/m³.
20,000 kg/m³.
What is the effect of temperature on the density of most substances?
Density remains constant with temperature.
Density increases with temperature.
Density decreases with temperature.
Density first increases and then decreases with temperature.
What are the units of density in the International System (SI)?
Gram per liter (g/L).
Newton per cubic meter (N/m³).
Kilogram per cubic meter (kg/m³).
Kilogram per liter (kg/L).
