Charge must come in specific-sized bundles. Only integer multiples of this smallest amount of charge can be found in Nature.
 
  What will be an ideal response?

Question 2

What is the temperature difference across a window if the conductive heat flow rate across it is 20 J/s? The window is 4.5 m2 in area that has an R-value of 2.5 m2 C/W.

Answer to Question 1

This statement is correct. The smallest size of charge found in Nature by
experiment (this experiment is known as the Millikan oil drop experiment) is 1.6 x 10-19 C.

Answer to Question 2

We find the rate of heat transfer from
rate of heat transfer = A DT/R = 4.5 m2 x DT/(2.5 m2 C/W).
This allows us to find DT. We have
DT = R x (rate of heat transfer)/A = (2.5 m2 C/W) x (20 J/s)/(4.5 m2) = 11.1 C.
