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 suchitas 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.

Explanation:

Step1: Analyze energy amounts

The heat energy is 400 J, light energy is 200 J and remaining chemical energy is 50 J.

Step2: Compare arrow - widths

Since heat energy (400 J) is the largest output energy value, its arrow will be the widest.

Step3: Evaluate other options

Initial chemical energy is not given as 50 J; chemical - energy arrow is not the shortest as it is 50 J and light is 200 J; there are multiple output arrows (heat, light, remaining chemical energy), not just one input and one output arrow.

Answer:

The arrow for heat is the widest output arrow.
