Answer:

The physical process of evaporation involves (1) addition of heat energy and (2) increase in entropy

Explanation:

During evaporation, liquid molecules convert into gas molecules. As gas molecules has negligible intermolecular force as compared to liquid molecules therefore heat energy has to be applied to separate liquid molecules by breaking intermolecular force and convert them into gas

Again, gas molecules are free to move. Hence they possesses more degrees of freedom. Therefore gas molecules have higher entropy than liquid molecules. So entropy increases during evaporation.

How many atoms are in 8.28 moles of aluminum?
Lilit [14]

Answer:

49.86 × 10²³  atoms of Al

Explanation:

Given data:

Number of moles of Al = 8.28 mol

Number of atoms = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

For example,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 8.28 moles of Al:

1 mole = 6.022 × 10²³  atoms of Al

8.28 mol×6.022 × 10²³  atoms / 1mol

49.86 × 10²³  atoms of Al
