Which best describes thermal energy?A.It is the difference between internal energies of two or more substances.
B.It is the sum of internal energies of two or more substances.
C.It is the portion of internal energy that can be transferred from one substance to another.
D.It is the portion of potential energy that can be transferred from one substance to another.
Answers
Thermal energy is the difference between internal energies of two or more substances. Therefore, option A is correct.
What is thermal energy ?
The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole field of physics that studies how heat is transmitted across various systems and how work is done in the process.
The average kinetic energy of the system's component particles as a result of their motion makes up the thermal energy of the system. The sum of the kinetic and potential energies of the system's component particles represents the system's overall internal energy.
Thermal energy is also referred to as heat energy. A moving object's kinetic energy is its energy. Thermal energy is a type of kinetic energy because it is produced by moving particles.
Thus, option A is correct.

ionic compounds lose or gain electrons to become stable.
ionic compounds are bonds between metals and nonmetals.
molecular or covalent compounds share one or more electrons to become stable.
molecular or covalent compounds are bonds between nonmetals.
Final answer:
An example of an ionic compound is sodium chloride (NaCl). An example of a molecular compound is carbon dioxide (CO2).
Explanation:
One example of an ionic compound is sodium chloride (NaCl), where sodium (Na) is a metal that forms a positively charged ion and chlorine (Cl) is a nonmetal that forms a negatively charged ion. The formula for a molecular compound is represented by carbon dioxide (CO2), where carbon (C) and oxygen (O) atoms share electrons to form covalent bonds.
