Intermolecular forces in solids are strongest than in liquids and gases. Gases have the least strong intermolecular forces. Intermolecular forces are weak and are significant over short distances between molecules (determined by Coulomb’s law). The farther away from the molecules the weaker the intermolecular forces. Since molecules in solids are the closest, the intermolecular force between them as the strongest. Conversely, since gas molecules are farthest apart, the intermolecular forces between them are the weakest.
The answer is 814.5 :
There is 3258 calories in one pound of margarine (according to google)
one-fourth= 0.25
0.25*3258= 814.5 calories
If the self ionization reaction is endothermic then it will shift on right side from equilibrium if we increase the temperature.
<h3>What is endothermic reactions?</h3>
Endothermic reactions are those reactions in which heat or energy is absorbed by the reactants for the formation of product.
If the self ionization reaction is endothermic in nature then in this condition at the equilibrium if we increases the temperature then the formation of ions increases as a result of the shift of the reaction towards the right side.
Hence, by increasing the temperature we can predict whether the reaction is endothermic or not.

Grams is smaller than kilograms but larger than milligrams
1g = 0.001 kg
1g = 1000 mg
Grams is an SI unit for mass.
International System of Units (SI Units) are organized body of measurements for physical quantity. They are set to be the norm or global norm scaling for every physical quantity which includes kilogram, meter, second, ampere, kelvin, candela and mole. These measurements then can increase or decrease by the power of ten, multiplied or divided. As said and explained, the SI is helpful in describing objects because
<span>1. They give us the idea of how much matter is contained in that single substance or the current state the matter is in or how hot or cold. We measure and can quantify the quality of the specific matter.</span> <span><span>
2. </span>SI Units are a global set of measurement hence, we can communicate with ease from western to eastern countries with these measurements without having problems in terms of portraying or displaying a set of physical quantities.</span><span> </span>
Answer: v = 2π2 Kme2 Z / nh
Explanation:
The formula for velocity of an electron in the nth orbit is given as,
v = 2π2 Kme2 Z / nh
v = velocity
K = 1/(4πε0)
m= mass of an electron
e = Charge on an electron
Z= atomic number
h= Planck’s constant
n is a positive integer.
