If the question is about what density derived from then it is mass and volume.
But if the question is about what would affect density, it would be pressure and temperature by ideal gas law.
Solid and liquid are mostly considered incompressible and the density would mainly varies with temperature yet the pressure still play effect on the density. For instance, ice at 1 bar could sublimate to gas if the pressure is reduce to 0.01 bar and the density would reduce drastically. Water at 25 C could be compressed to solid at 10,000 bar and density would increase from 1 kg/L to 1.3 kg/L at such pressure.
Whether small things float or not depends on their density. If the density of an object is less than the density of the fluid it is placed in (such as water), then it will float. However, if the density of the object is greater than the density of the fluid, it will sink.
No, whether an object sinks or floats depends on its density compared to the density of the fluid it is placed in. An object with a lower density than water will float, while an object with a higher density will sink. The weight alone does not determine if the object will sink or float.
Lift depends on factors such as the shape of the object (e.g., airfoil shape), airspeed, angle of attack, and air density.
Yes. For every fluid, there are things that float in it ... they just have to be things that are less dense than the fluid. That's how stones float in mercury, logs float in water, and hot balloons float in air.
The speed of any mechanical wave depends on the medium through which it is traveling and the properties of that medium such as density and elasticity. In general, waves travel faster through medium with higher elasticity and lower density.
Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
Salt water density really depends on a few different things. The concentration of salt and temperature are the 2 largest factors in determining the density of salt water.
muscle density and bone density
Depends WHAT the dry is. -things have different density.
Not necessarily. Density is mass divided by volume. Many different things could have the same density.
Depends on the density of your material.
That depends on the density of the material.
Whether small things float or not depends on their density. If the density of an object is less than the density of the fluid it is placed in (such as water), then it will float. However, if the density of the object is greater than the density of the fluid, it will sink.
the temperature and the salinity
No, whether an object sinks or floats depends on its density compared to the density of the fluid it is placed in. An object with a lower density than water will float, while an object with a higher density will sink. The weight alone does not determine if the object will sink or float.
it depends on the mass of the object. The equation for density is Mass/Volume=Density. if the volume just happened to be 10.52 Grams, the the density would be exactly 2 since 10.52/5.26=2
Lift depends on factors such as the shape of the object (e.g., airfoil shape), airspeed, angle of attack, and air density.
