Yes, basically. The density will change, but in the case of a liquid, the change is quite small, for most practical purposes.
No, the amount of a liquid is volume. Density is independent of volume.
The best way would be to change the state of the water. In other words, have ice floating in liquid water, while steam is above that.
yeah.....it does change when you add some liquid to it......
The buoyant force is equal to the 'weight' of liquid that is displaced, which depends on the volume of liquid that is displaced, the density of the liquid, and gravitational acceleration, not the weight of the body.
Whether or not the density changes if some of the liquid evaporates between the time the liquid is delivered to the beaker and the time it is measured depends on the liquid. For almost all liquids, the answer is no because there was not enough time. Water will have a density of approximately 1 and if a small amount evaporates, it will still have the same density. If you had the beaker at 100C and the room at 0C and waited until the water was 4C, it would make a difference. If the water was at 40C and the room was at 30C, it would almost make no difference. A very few substances would undergo tremendous cooling. That would bring a corresponding increase in density.
how heat would change the density of a parcel of air?
If you put a ice cube in a pan in a warm room the two physical properties that will change would be shape. Another property would be density.
It isn't clear what units you are using, what liquid you are placing it in, and whether that is the density of the object or of the liquid. The general rule is that an object will float if it has less density than the liquid in which it is placed.
The density of water does not change with volume of water but it can change when the temperature is close to a phase change ie 100 oC or 0 oC. Density = mass / volume Density of water = 1.0 g /cm3
This question is dependent on the exact type of liquid. For example as it cools to freezing ice is actually less dense than liquid water. This is the reason for ice having the ability to float.
