If one side is pointed at the sun it has more day light hour because it pointing at the sun. and the temperature is high because it is close to the sun
According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.
<h3>What is Kinetic molecular theory ?</h3>
Kinetic molecular theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules.
According to this theory, gas pressure arises due to particles colliding with each other and the walls of the container.
Because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.
This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Due to the sun's heat, the kinetic energy of particles in the balloon increases and it expands and continues to expand and comes to a stage when the balloon bursts.
Therefore,
According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.

The question is incomplete, the complete question is;
Why was it necessary to make sure that some solid was present in the main solution before taking the samples to measure Ksp? Select the option that best explains why. Choose... A. To make sure no more sodium borate would dissolve in solution. B. To ensure the dissolution process was at equilibrium. C. To make sure the solution was saturated with sodium and borate ions. D. All of the above
Answer:
B. To ensure the dissolution process was at equilibrium.
Explanation:
The solubility product is a term used in chemistry to describe the equilibrium between the dissolved, dissociated and undissolved solute of a relatively low solubility ionic solid.
For an ionic solid MX, the solubility product is given as ;
MX(s) ----> M^n+(aq) + X^n-(aq)
If Ksp indeed scribes an equilibrium process for dissolution, it then implies that some undissolved solute must be present before samples are taken to measure the Ksp of a sample. This ensures equilibrium between dissolved and undissolved solute.
Answer:
<u></u>
Explanation:
The current temperature and pressure at <em>STP </em>(Standard Temperature and Pressure) stated by IUPAC are:
- Temperature: 273.15 K (0 °C)
- Pressure: 10⁵ Pa ≈ 0.9869 atm
Using the <em>ideal gas </em>equation, pV = nRT, and the Avogadro constant, you can find the<em> volume occupied by 5.80 × 10²⁰ molecules.</em>
