Answer:
A
Explanation:
For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade or water your crops or yard. It is the invisible process of evaporation that changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds.
The correct statement is that the average kinetic energy of the gas particles is greater in container A because its particles move faster.
<h3>What is the relation between temperature & kinetic energy?</h3>
Kinetic energy of any particle is directly proportional to the temperature of the sample of that particle.
From the given diagram, it is clear that:
- In beaker A, heat is supplied to the beaker due to which temperature of the beaker A increases as a result of it particles of gases will move with faster velocity because kinetic energy of the gases particle increases.
- Beaker B is present at room temperature, so particles in this beaker will have less velocity as compared to beaker A.
Hence, the average kinetic energy of the gas particles is greater in container A because its particles move faster.

Answer:
0.99%
Explanation:
The Henderson-Hasselbalch equation relates the ratio of the ionized to the non-ionized form of an acid as follows:
pH = pKa + log([A⁻]/[HA])
Inserting the values for pH and pKa and solving gives:
7.4 = 5.2 + log([A⁻]/[HA])
2 = log([A⁻]/[HA])
[A⁻]/[HA] = 100/1
The percentage of the weak acid in non-ionized form (HA) is then calculated:
[HA]/([A⁻] + [HA]) = 1/(100+1) x 100% = 0.99&
