Evaporating water is an example of a physical change because (2 points) question 7 options: 1) bonds are broken and atoms are rearranged. 2) the atoms are pulled apart to form a new substance. 3) it does not involve intermolecular forces or particle motion. 4) the identity of the substance does not change.

4) the identity of the substance does not change.

Explanation: Chemical change is defined as the change in which a change is the chemical composition takes place resulting in the formation of new substance. It is usually an irreversible reaction.

Physical change is defined as the change in which shape and size of a substance changes, There is no change in the composition of the substance as no new substance is forming. It is usually an reversible reaction.

When a liquid evaporates, the liquid water changes to gaseous form and thus the identity of the substance does not change.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
