Explanation:
This graph shows that an increase in altitude causes a relative decrease in boiling point temperatures. The two variables, it can be said, are inversely proportional.
This is because, with an increase in altitude, there is a proportionate decrease in air pressure. This means the vapor pressure of the fluid becomes strong enough, at a relatively lower temperature, to overcome the air pressure and for the liquid to boil.
This is why water can even boil without inputting heat into it but rather by just reducing the ambient air pressure.
The product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.
<h3>What is the reaction between sulfuric acid and potassium hydroxide?</h3>
The result will be, H+ from H₂SO₄ reacts with OH- from KOH to generate H₂O. Also, K+ reacts with SO₄²⁻ to create K₂SO4₄
As a result, the balanced equation will be:
Thus, the product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. Sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

Answer:
The correct option is: D. A suspension
Explanation:
A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.
<u>Therefore, in the given situation, the chicken broth is </u><u>a suspension</u><u> </u>as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.
B
<u>Collisions between gas particles and the object</u> is the reason a gas exerts pressure on the object.
Explanation:
Gas molecules usually have higher kinetic energy than that of liquid and solids. These molecules, therefore, collide with other molecules of the gas and if the gas is held in a container, the gas molecules will also collide with the walls of the container. As the kinetic energy of the gas molecules increases, due to increased energy input in the gas, so does the energy of collisions between the molecules and the molecules with the walls of the container. This is how the pressure of a gas in a container increases with an increase in temperature.
Even though the gas molecules are tiny, the numerous collisions by the billions of gas molecules of the gas apply a cumulative pressure.
