Answer:
Boiling Point and Melting point = Condensation Point and Freezing Point
Explanation:
Such is easily seen on the 'Heating Curve for Water' (see attached). Note the regions that have zero slope. Trace back to y-axis of graph. These points are the phase transition temperatures for freezing (Iiquid => solid)/melting of ice (solid => liquid) and boiling of water (liquid => gas) / condensation (gas => liquid).
Note also, during phase change (heating or cooling), two phases will always be present (solid & liquid) or (liquid & gas) and experience 0 temperature change during the transitions (zero slope regions). The regions having slope values are heating or cooling of pure single phase form of the substance and do not represent phase change in those regions.
Answer: The answer is O and F
which is oxygen and flourine

<u>Answer:</u> The pH of the cleaning compound is 10.44
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.
The equation representing pH of the solution follows:
We are given:
Putting values in above equation, we get:
Hence, the pH of the cleaning compound is 10.44
Answer:
Option-D : <span>Decrease the velocities of the particles, and decrease the space between the particles.
Explanation:
The solid state of matter is composed of particles closely packed with a minimum space between them. This closed packing of particles occur due to strong interatomic or intermolecular interactions between particles. Therefore, solids particles have zero translational and rotational motions and only show vibrational motions. So, decrease in velocity and decrease in space between particles is the right answer for making solids.</span>
