An electrically isolated object is electrically neutral. what is the charge on the object if you remove three electrons?

Explanation:

The initial charge of the object is zero, since the object is neutral:

Q = 0

When we remove three electrons, we remove a charge of:

where

is the charge of one electron. Substituting,

So, the final charge on the initially neutral object will be

ice to water 1 water to vapour 2 latent heat
