Can a material be a single compound when it is physically separated?
Yes it can be. An example of this is when two phases of a material are in the same system, such as ice cubes in a glass of water. The compound is still H2O, but there are two different phases of water that are easily separable.
What injury results when two bones that comes together to form that joint become separated?
Where two bones come together or "join" is called a "joint".
Can the hydrogen and oxygen created by the electrolysis of water be easily recombined to create pure water?
Yes, the pair of gases can easily be combined to create pure water. Passing the two gasses across a hot surface will cause the hydrogen and oxygen to "burn" or recombine, and (pure) water will form. The water will appear as a hot gas, but cooling it will cause it to condense.
How do you weld plastic?
They use a tool that looks like a hot air gun. It heats the plastic to the correct temperature and melts the filler material at the same time. Remember, welding is melting and fusing material whether it is metal, plastic, or glass. Sometimes they do what is called chemical welding. Then they coat the two pieces to be welded with a solvent that dissolves the outer layers. They mate the two pieces until the solvent evaporates. After the solvent is gone, the two pieces have merged along their edges and are "welded" together.
How a mixture of sand and benzoic acid which is soluble in hot water might be separated to provide benzoic acid?
Sand is insoluble in water and can be easily filtered.
List two materials that become hot easily?
There are a wide variety of materials that become hot easily. Two examples would be leather and asphalt. Both can become extremely hot in just a matter of minutes.
What happens when a cold material interacts with hot material?
The heat from the hot material is transferred to the cold material. Given enough time, eventually the two materials will be the same temperature, and no more heat will be transferred between them.
How can materials become electrically charged?
Material can become electrically charged when two different material are brought into close contact, some of the electrons move from one material to another.
In which of these does hot material rise and cool material fall?
In a liquid (as solid particles in a liquid or in a lava lamp with two immiscible liquids) In the air, hot air rises, cold air descends (as in a hot air balloon)
What are the two factors determine how easily water moves through a material?
Two Factors are the type of material. The best material water moves through is a partially permeable membrane. Another factor is the substances dissolved in the water and the substances inside the material. There can also be if there are pores that are connected.
What material allows heat or electricity to pass through it easily Give two examples.?
metal and metal and plastic
What are two ways a gas can become a liquid?
Evaporation and Extreme Hot or Cold

How do you get what ever you want?
Two options: Become a cartoon character Be a really hot woman
What are some negative effects of friction?
Static. and when you rub two objects together it will become warm or hot
When two or more materials are combined together to form a composite material they become identifiable macroscopically true or false?
true
When do chromosomal material replicate?
Chromosomal material replicates during mitosis. Chromosomes become sister chromatids, which ultimately break off to form identical chromosomes and two identical cells.
