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.

6.3 × 10²⁵ atoms of O
Explanation:
Thus, 9.4 mol of C₁₂H₂₂O₁₁ contains 6.3 × 10²⁵ atoms of O.
Answer:
The order is
Quartz > Calcium > Ammonia > Chlorine
Explanation:
Among given compounds
Quartz is a covalent compound with extensive bondings and thus it will have highest melting point
Calcium is a metal so it will have strong metallic bonds thus will have high melting point, however less than quartz.
ammonia is a polar molecule with weak hydrogen bond as intermolecular interactions thus will have higher melting point than chlorine
chlorine is a non polar molecule with weak intermolecular london dispersion forces.
