Which of the following changes made to a sample of liquid would result in an increase in the distance between the individual molecules of the substance?Transferring the substance to a smaller containerAdding heat energy to the substanceChanging the phase of matter from liquid to solidDecreasing the overall kinetic energy of the liquid

Adding heat energy to the substance

Explanation:

Adding heat energy to a liquid sample would result in an increase in the distance between the individual molecules of the liquid.

According to kinetic molecular theory of matter, the more the temperature of a substance, the more the kinetic energy of the molecules of the substance.

Heat increases the temperature of a substance. The addition of heat to a substance therefore increases the average kinetic energy of the molecules of the substance.

Also, the more the kinetic energy of the molecules in a substance, the more likely for the molecules to drift apart, that is, the average amount of empty space between molecules gets larger.

Hence, the addition of heat energy to a liquid sample would result n an increase in the distance between the individual molecules of the liquid.

the answer is   c.) 1575 j.

explanation:

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
