Scientists observe patterns in how molecules interact with each other. At the same temperature, for example, liquids have more a

ttraction between particles than gases do. Water (H2O) is a liquid at room temperature, while carbon dioxide (CO2) is a gas at room temperature. Why? Choose the two statements that apply.
A. Nonpolar molecules only attract polar molecules.
B. Polar molecules attract each other more than nonpolar molecules do.
C. Water molecules are polar. Carbon dioxide molecules are not.

Match the correct definition with the correct term from questions 10-13: A. Internal energy B. Latent heat C. Chemical (bond) en
Marizza181 [45]

Answer:  A. Internal energy : May be viewed as the sum of the kinetic and potential energies of the molecules

B. Latent heat: The internal energy associated with the phase of a system.

C. Chemical (bond) energy : The internal energy associated with the atomic bonds in a molecule

D. Nuclear energy : The internal energy associated with the bonds within the nucleus of the atom itself

Explanation:

Internal energy is defined as the total energy of a closed system. Internal energy is the sum of potential energy of the system and the kinetic energy of the system. It is represented by symbol U.

Latent heat is the thermal energy released or absorbed by a thermodynamic system when the temperature of the system does not change. It is thus also called as hidden heat.

Chemical energy is the energy stored in the bonds of molecules.

Nuclear energy is the energy which is stored in the nucleus of an atom called as binding energy within protons and neutrons.

Matter is made up of heat energy and ___________energy?
ella [17]
You’re correct, matter is made up of heat energy and chemical energy

all matter contains heat because it is the result of the movement of atoms, molecules, or ions in solids, liquids, and gases.

all matter also contains chemical energy. chemical energy is stored in the bonds of chemical compounds so atoms and molecules are held together by chemical energy

hope this helps :)
