Explanation:
A) it is endothermic and heat is absorbed by the system.
Answer:
Mass = Number of neutrons + Atomic number (aka number of protons)
Explanation:
Answer is: atoms have the greatest kinetic energy in <span>liquid iron (2,000°C).
</span>The average kinetic energy of molecules depends on the temperature.
At high temperature(2,000°C), molecules of iron have greater kinetic energy than molecules of iron at low temperature (1,600°C, 65°C and 25°C)..
