Answer:
The thermal energy is the average kinetic energy of the particles in an object.
Explanation:
Hello!
In this case, since the thermal energy is associated to the temperature and the system and its effect over the molecules in the light of their movements, we infer that the proper answer is:
"The thermal energy is the average kinetic energy of the particles in an object".
On the contrary, we consider that the internal energy is referred to the total energy of the particles in the system and the translational energy is associated to the eventual movement of the system.
Best regards!

<u />
= 7 mol Fe
<u>Step 3: Check</u>
<em>We are given 1 sig fig.</em>
Since our final answer is in 1 sig fig, there is no need to round.
Answer:
198g
Explanation:
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
Number of mole of CO2 = 4.5moles
Mass of CO2 =?
Mass = number of mole x molar Mass
Mass of CO2 = 4.5 x 44 = 198g
