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.
