Because some objects are a lot denser than water so the sink and others are less denser so they float
Yes. The salt stabalizes them in the water. If you have ever heard of the dead sea, anything really can float in there. If there is salt in water a peanut can float.
Sea Glass Is Made From Glass Objects That Were Disgarded Into The Ocean Many Years Ago And Have Spent Their Time Tumbling Against The Waves And Sand. Since Sea Glass/Beach Glass Is Made From Glass, It Does Not Float.
It depends on the density of an object. If the density is higher than the density of the liquid, the it sink. If it's less, it floats.
Whether an object floats or not depends on its density. Density is the amount of mass in a volume, or mass divided by volume. If and object's density is less than that of water, it will float in water, and if an objects density is higher than that of water, it will sink in water. raw material (fishballs will sink down);but it will floats when it is cook. why
No, because a hockey puck has a higher density than water. In some cases, objects with higher density than water can still float on the water, if they are small enough to avoid breaking the surface tension of the water. This is also the case if the object's mass is distributed across a large enough area, so you could float a penny on water if you put it down flat across the water, but it would not float if you dropped it in on its side. You also could not float that penny if you melted it down and made it into a sphere, for example.
Because some objects are heaver than others.
because some objects are much denser(heavier) than water so they sink
No, some sink.
It's far from clear what the actual question is. Some objects float in both salt and fresh water, some objects float in neither, and some objects float in one but not the other. Any object that floats in fresh water will float in salt water, but the reverse is not true.
The types of objects that will float on water are foil, most rubber, and some plastic.
The density of water is called "1.0" Certain objects have a mass greater than 1.0, therefore they will sink. Objects with densities less than 1.0 will float or remain partly submerged.
Well some do - mineral spirits for example are a hydrocarbon that do float on water. However, others such as methylated spirits are totally water soluble and hence dont float.
It is to do with to volume and mass.
Objects float in water if they have a density lower than water, while objects sink if they have a density higher than water. Density is a measure of how much mass per unit volume an object has. This is why objects like wood and plastic, which have lower density than water, tend to float, while objects like metal, which have higher density, tend to sink.
On some liquids it will float, on others it will not.
Styrofoam
Some objects that float on milk are coins, cork, small plastic toys, and seeds like sesame seeds or chia seeds.
