Question

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.

Answer 1

Suchita’s energy transfer diagram will show 'The arrow for heat is the widest output arrow,' since it represents the largest energy transformation of 400 J from the fuel.

Step-by-step explanation:

The statement that describes Suchita’s final diagram for the energy transformations associated with the flame of a gas stove is that 'The arrow for heat is the widest output arrow.' This is because in her energy transfer diagram, the chemical energy of the fuel transforms into different forms of energy, with 400 J going to heat, 200 J to light, and only 50 J remaining as chemical energy. The width of the arrows in energy transfer diagrams typically represents the magnitude of the energy transfer, with wider arrows depicting greater amounts of energy. Since 400 J is the highest energy transfer here, the heat arrow should be the widest.

Answer 2

the answer the the question is, B.
