Answer:

smaller, greater

Explanation:

Moving from left to right in the periodic table, we notice that the magnitude of nuclear charge increases with increasing atomic number.

Recall that across the period, nuclear charge increases without a corresponding increase in the number of shells hence the size of the atom (atomic radius) contracts due to a greater pull of the nuclear charge on the electrons.

A gas with a volume of 8 L at a temperature of 473K is switched to a new container with a temperature of 350K. If the pressure r

Answer:

The new volume is 5.92 L, which is approximately 6 L

Explanation:

As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.

So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
