Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.

In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by _____.
A) hydrogen bonds
B) nonpolar covalent bonds
C) polar covalent bonds
D) ionic bonds
Answer:
C) polar covalent bonds
Explanation:
Polar covalent bonding can be regarded as a chemical bond that involves a pair of electrons which is
unequally shared between two atoms.
The electron are not shared equally as a result of one of the atom spending more time with the electron compare with the other atom. It is one whereby atoms having different electronegativities involves themselves in sharing electrons in a covalent bond

The sun radiates energy towards the ______ surface and some of this radiant energy is in the form of ________.
Answer:
Earth; heat.
Explanation:
Radiation can be defined as the flow, transmission or emission of energy in the form of atomic and subatomic particles and waves through a material medium or space.
Solar radiation is a form of electromagnetic radiation emitted by the sun on the earth's surface as ultraviolet, infrared and visible light.
Hence, the sun radiates energy towards the earth surface and some of this radiant energy is in the form of heat. Radiation is generally considered to be the least important mode of the transportation of heat from one point to another in planet earth.

Chemistry help needed! (picture included)
Answer:
Use a fine, crystalline solute and stir vigorously
Explanation:
It is better if it is fine instead of coarse since this will provide more surface area. If there is more surface area, the crystals will dissolve faster.
You also have to stir the solution vigorously to keep all of the crystals exposed to the solvent.

From point A to point B, the car will . From point B to point C, the car will assuming the washer on the car is not blocked . It will examine Newton’s law will be "Accelerate, Have Constant velocity, Velocity, and First."
What is Newton’s law ?The link between an object's motion with even the forces acting on it is outlined by Newton's laws of motion, which were three fundamental principles of classical mechanics.
What is velocity?The displacement of the item in one unit of time would be the definition of velocity.
Therefore, from point A to point B, the car will . From point B to point C, the car will assuming the washer on the car is not blocked . It will examine Newton’s law will be "Accelerate, Have Constant velocity, Velocity, and First."

A student is instructed to design a device that can allow one user to hear a voice of another surer a distance of 5 kilometers which statement describes the most applicable basic design concept
Answer:
A device designed to transmit electromagnetic waves through the air should be developed.
In order to meet the requirement a device is designed to transmit electromagnetic waves through the air should be developed.
What are electromagnetic waves?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.
