A solar water heating system uses a large storage tank to store thermal energy collected during the day. This stored energy is then used to heat water for household use during the night. Which combination of thermal capacity of the water tank and daytime temperature increase will result in the most thermal energy being stored?
Large thermal capacity of the tank, large daytime temperature increase
Large thermal capacity of the tank, small daytime temperature increase
Small thermal capacity of the tank, large daytime temperature increase
Small thermal capacity of the tank, small daytime temperature increase
