Select all that apply. if a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster

Explanation:

When heat is provided to a substance then it means we are increasing the temperature of substance. Also, the molecules will start to move due to the heat provided.

As a result, intermoleculear bonds will break, that is, there will be decrease in intermolecular bonding to the molecules. Therefore, molecules will gain kinetic energy.

Thus, they will start to move rapidly from one place to another.

Hence, we can conclude that if a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, then:

No. of Persons= 16

Step-by-step explanation:

There was a one phone line

Average no of people calling = 60 in one hour

% of all callers at most can get busy signal

Probability < 0.6

Probability for less than 1 person on hold = 0.2642

No of persons = 0.2642(60)

= 15.852 or 16

16 persons in hour the company is able to put on hold
