This energy required is the latent heat, which is required for physical transformations. Specifically, when it involves changing liquid to gas, this latent heat is called the heat of vaporization. The formula is:
Q = mΔHvap
The molar mass of the compound is
Q = (48.7 g)(31.6 kJ/mol)(1 mol/84.93 g)
<em>Q = 18.12 kJ</em>
Because they insulate either the heat or the coolness within the food item. But keep in mind- when it comes to electricity aluminum isn’t an insulator.

If it was helpfull, please select as brainliest answer. thanks;)
The given data is as follows:
Element 1st IE
1 1310 kJ/mol
2 1011 kJ/mol
3 418 kJ/mol
4 2080 kJ/mol
5 947 kJ/mol
Ionization energy is the amount of energy required to remove an electron from an atom. It reflects the tendency of an atom to give away electrons readily. Lower the IE, more easily will the electron be lost. Low values of IE are characteristic of metals whereas, non-metals have higher IE values.
Based on the given data:
Element 4 is likely to be a non-metal
Element 3 is likely to be a metal
Roll until stopped by a force
Because an object in motion will stay in motion unless acted upon by an outside force
