Thermal Energy<span>. </span>Thermal energy<span> is the internal</span>energy<span> of an object due to the kinetic </span>energy<span> of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic</span>energy<span> than those of a colder one, in the form of vibrational, rotational, or, in the case of a gas, translational motion.</span>
If the precipitate of CaSO4 was weighed before all of the
water has evaporated, therefore this will lead to a miscalculation on the
number of moles of CaSO4. During the calculation, the mass of the water will be
included hence there will be higher number of moles than what is correct.
One atom of carbon weighs exactly 12/6.022x10^23 = 1.9927x10^-23 grams<span>.</span>
