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 arrow for heat is the widest output arrow.

The arrow for chemical energy is the shortest output arrow.

Explanation:

here by the law of energy conservation we can say that

Total energy that is used or consumed must be equal to the total energy that is transferred in different forms

So here we will say that

here output energies are given as

1. chemical energy = 50 J

2. Heat = 400 J

3. Light = 200 J

so here in output energy form we will get maximum energy in form of heat so the arrow related to this must be widest in size

While the chemical energy is minimum output energy so here the least size arrow will be of chemical energy

the answer is b ) square root of 5
