Answer:
B.
Explanation:
To solve this we must be knowing each and every concept related to phase diagram. Therefore, the correct option is option B among all the given options.
What is phase diagram?A phase diagram is a graphic that depicts a substance's thermodynamic state at various pressures and temperatures. The areas surrounding the lines represent the phase of both the material, and the lines represent the points at which the phases are all in equilibrium.
A phase diagram often contains lines of equilibrium and phase boundaries. Multiple phases like matter can exist in equilibrium along these lines. The lines also illustrate the locations of phase transitions. Phase diagram tells about the effect of temperature and pressure on the phase of a substance.
Therefore, the correct option is option B among all the given options.

Who is correct? Reggie, because baking and melting cause bonds to be broken, leading to a chemical change. Reggie, because objects that are heated always undergo chemical changes. Charlotte, because melting objects only sometimes cause a chemical change. Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.
Answer: Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.
Explanation: Baking is a chemical change you cant turn it back to what it was before. Its chemical properties have changed. Melting is a physical change. Its chemical properties are still the same it has not changed. It just changed it's physical form but the object is still the object.
Answer:
Charlotte, because baking causes a chemical change, but melting objects is a non-chemical change.

Which describes a climate effect on the rate of weathering? Cold climates favor mechanical weathering. Chemical reactions occur slower at higher temperatures. Lower precipitation levels lead to more chemical reactions. The chemical reaction rates of minerals are not impacted by temperature.
Answer:
the answer is Cold climates favor mechanical weathering.
Explanation:
I got 100% on the Quiz
Statement that describes climate effect on the rate of weathering as regards this question is A:Cold climates favor mechanical weathering.
Weathering can be regarded as disaggregation of rocks into smaller bits by the actions of agents of weathering such as man, animals, water and so on.However, climate can also have effect on the rate of weathering, when there is cold climate, mechanical weathering is favoured.Option B,C,D are wrong because high temperature brings about increase in rate of chemical weathering.
Therefore, option A is correct.

Which of the following would have the best thermal conductor properties?
A. A thick mug
B. A plastic cup
Ос. A paper cup
D. A cup made of metal
Answer:
D
Explanation:
metal is a major cunductor of heat
A cup made of metal would have the best thermal conductor properties.
The answer is option D.
Is a metal cup a good conductor of heat?Metals have unfastened electrons that are not bounded to the atoms. those electrons are unfastened to move around within the metal, colliding with the metal atoms and shifting heat to them successfully. This makes metals higher conductors of warmth than maximum other materials.
Which of the following would have a high-quality thermal conductor?Diamond is the leading thermally conductive material and has conductivity values measured 5x better than copper, the maximum synthetic metallic inside the united states of America. Diamond atoms are composed of a simple carbon spine this is a really perfect molecular structure for an effective heat switch.

5. Which type of substances do you separate into lons when writing the complete lonic equation?
Answer:
As a general rule, soluble ionic compounds, strong acids, and strong bases should be written as dissociated ions in the complete ionic equation. Insoluble salts and weak acids are written using the neutral molecular formula since they only dissociate to a very small extent in water.
