The form of energy stored in a wound-up spring toy.
The type of energy the toy has when it is going.
The effect on energy when the when the toy runs down.

Explanation of Solution
Introduction:
Potential energy is the energy by virtue of a body’s position or its shape. Kinetic energy is the energy in a body by virtue of its motion.
When a spring is wound up, it stores potential energy. When the toy moves, the potential energy is converted to kinetic energy. When the toy runs down, all the potential energy is converted to kinetic energy.

Required information The PV diagram shown is for a heat engine that uses 1.030 mol of a diatomic ideal gas as its working substance. In the constant-temperature processes A and C, the gas is in contact with reservoirs at temperatures 373 K and 273 K, respectively. In constant-volume process B, the gas temperature decreases as heat flows into the cold reservoir. In constant- volume process D, the gas temperature increases as heat flows from the hot reservoir.
