Answer: The atoms in a gas move at high speed.
The atoms in a gas spread in all directions.
A gas is a state of matter in, which atoms remains in a constant motion, they do not stick together. They are free and can move in all directions. The gas molecules expands to fill the available space. Hence, they can change shape and volume. The gas atoms being in a molecular state moves fast in high speed to break away from each other, to remain in a free state.
Answer:
it will turn to ice
Explanation:
the potential energy in the molecules is reduced and they start to move alot slower, eventually they stick together and form ice
The iceberg has weight Wi = Mig and the buoyant force is equal to the weight of the displaced water, Ww = Mwg. Furthermore, since the iceberg is floating, its weight exactly balances the buoyant force:
Ww = Wi
Mwg = Mig
VwRhowg = ViRhoig
Vw = Rhoi/Rhow Vi
So, the fraction of ice underwater, Vw/Vi, is given by the ratio of densities Rhoi/Rhow=0.87. Over 87% of an iceberg's volume (and mass) is underwater. As you can see, the convenient definition of the gram gives us a quick way to see how much of a floating substance lies below the surface of fresh water: the fraction is equal to that substance's mass density in g/cm?.
Summary
<span>Archimede's Principle of bouyancy states that the bouyant force on an object is equal to the weight of the fluid displaced by that object.<span>The underwater fraction of a substance floating on water is given by that substance's mass density in g/cm3.</span></span>
Answer:
Mohammed should now <u>lift</u> the print from the surface to preserve it
Explanation:
In order to preserve fingerprint evidence as required by crime laboratory policies and criminal justice systems, for which we have digital photography, casting material, and latent print lifts, that can be used as secondary evidence
The ridges on the cast and lift can be photographed to serve as an additional secondary evidence
The processing of the latent print after photographing is dependent on the surface type and may include the creation of an impression on soap, paint, wax, clay or dust
Therefore, Mohammed used an enhancement technique that made a fingerprint visible on a lamp. He photographed the print. Mohammed should now <u>lift</u> the print from the surface to preserve it
