<span>When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase. For example, ice melts and becomes water; water evaporates and becomes water vapor.These changes of phase always occur with a change of heat. Heat, which is energy, either comes into the material during a change of phase or heat comes out of the material during this change. However, although the heat content of the material changes, the temperature does not.</span>

HELP QUICKK PLEASEEE

Answer:

According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

Which of the following halogens has the largest atomic radius?

pickupchik [31]

Answer:

$\boxed {\boxed {\sf B. \ Iodine }}$

Explanation:

Atomic radius is the measurement from the nucleus to the outer edge of the electron cloud.

As you go down a group (vertically) the atomic radius increases because more electron shells are added. As you go across a period horizontally, the atomic radius decreases.

If we look at the halogens group (17), we see they follow this order from top to bottom:

F - Fluorine

Cl - Chlorine

Br - Bromine

I - Iodine

Since it increases down the group, iodine must have the largest atomic radius.
