Suchita is going to make an energy transfer diagram to represent the energy transformations associated with the flame of a gas stove. The diagram will show that the chemical energy of the fuel transforms into 50 J of chemical energy, 400 J of heat, and 200 J of light.

Which statement describes Suchita's final diagram?

The initial chemical energy is 50 J.

The arrow for heat is the widest output arrow.

The arrow for chemical energy is the shortest output arrow.

There is one arrow for input and one for output.

The answer the the question is, B.

Pogo · Answer 2

In energy diagrams, the width of an arrow is used to represent the amount of energy that is flowing. Therefore, greater amount of energy are represented by wider arrows and smaller amounts of energy are represented by narrower arrows. Using this, we can conclude that the arrow for heat is the widest arrow.
