Why does the heat rise in convection?
There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.
What is the difference between an objects that float and the objects thasink in water?
Objects that float in water are less dense than water; while objects that sink in water are more dense than water.
What type of water would a swimmer float more easily?
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!
What force in fluids described by Archimedes'principle allows objects to float?
bouyancy
What principles allow fluids to float?
A liquid that is less dense than water will float - oil being one example.
How do objects float in salt water?
An object will float when it is less dense than the liquid around it. Because saltwater is denser than freshwater, it is easier for an object to float.

What do objects that float have in common?
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
What force in fluids allows objects to float?
Buoyancy
Why do dense objects float in the dead sea?
it is salty and salty waters are dense
Do objects float better in dense water?
yes
What do objects that float all have in common?
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
What objects float in water?
objects that are less dense float to the top.
What type of water would a swimmer float more easily?
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!
What are the objects that can float on water?
Any object that is less dense than water will float.
Is it easier to swim in saltwater?
When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.Because objects float better on a dense surface, they float better on salt water than fresh water. The denser the salt water, the easier it is for objects to float on top of it.
