Which statement is the best explanation for the graph? (1 point)
1. As temperature rises, gas particles are moving faster and are more
likely to enter the solution.
2. As temperature rises, the space between liquid particles decreases,
leaving less room for gas particles.
3. As temperature rises, gas particles are moving faster and may leave
the solution.
4. As temperature rises, the space between liquid particles increases,
allowing more room for gas particles.

The statement that correctly explains the graph attached is: "As temperature rises, gas particles are moving faster and may leave the solution."

We know that the solubility of a gas decreases with increasing temperature. This stems from the fact that the kinetic energy and velocity of gas molecules increases with increase in temperature.

That means that as a the temperature of a gas increases, its molecules move faster and are more likely to escape from solution rather than enter the solution.

This explains the decrease in the solubility of a gas with increase in temperature.

Explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
