neutral - electrons cancel out the positive charge of the atom

A student burns heats up a piece of orange and some oil. Then he places them in a beaker with water and records the changes in the temperatures. Which food item will hold the temperature for the longest?

The oil, because it has many H-bonds which will cause it to hold the energy the longest

The orange, because it is a sugar and sugars give energy

The oil, because the oil is a sugar and it gives energy

The orange, because it has many H-bonds which will cause it to hold the energy the longest
