Answer:  65.4^0C

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

K=\frac{3RT}{2}

R= gas constant

T= temperature in kelvin

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is more, average kinetic energy of the system is more and vice-versa.

a. 18^0C=18+273=291K

b. 20.4^0C=20.4+273=293.4K

c. 36.2^0C=36.2+273=309.2K

d. 65.4^0C=65.4+273=338.4K

Thus substance at 65.4^0C will have greatest kinetic energy.

Which interaction occurs when light goes into an object as heat energy?
Rufina [12.5K]

Interaction occurs when light goes into an object as heat energy is Absorbed light.

Absorbed light makes an object dark. Absorption of light is when the light is absorbed by the object and converts it into heat energy. The objects converts the wavelength of light into the larger wavelength of heat.  this makes the object warmer and produced energy. Absorption depends on the frequency of light that is transmitted. The wavelength of light defined as the distance between the the two successive troughs of the the light wave.

Therefore, Interaction occurs when light goes into an object as heat energy is Absorbed light.

Which substance contains bonds that involve a transfer of electrons from one atom to another
cestrela7 [59]
An ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms.
