In a roller coaster, both the kinetic and potential energy in the car decreases at
Lemur [1.5K]

We can confirm that in a roller coaster, kinetic and potential energy in the car decreases at  each successive hill because of  the force of gravity which converts potential  energy into  kinetic energy.

<h3>What are potential and kinetic energy?</h3>
  • Potential energy is referred to as <em><u>positional energy</u></em>.
  • This means that the object in question gains energy based on its position relative to others.
  • Kinetic energy is the energy of movement.
  • Gravity causes the roller coaster to fall, losing potential energy.
  • This causes it to gain all of the potential energy as kinetic energy.
  • Once at the bottom, the coaster no longer moves and thus loses the kinetic energy as well.

Therefore, we can confirm that gravity is the force that causes the shift from potential energy to kinetic energy and thus causes them both to decrease after each successful hill in the roller coaster.

Answer:

The answer to your question is     V2 = 4.97 l

Explanation:

Data

Volume 1 = V1 = 4.40 L                    Volume 2 =

Temperature 1 = T1 = 19°C               Temperature 2 = T2 = 37°C

Pressure 1 = P1 = 783 mmHg           Pressure 2 = 735 mmHg

Process

1.- Convert temperature to °K

T1 = 19 + 273 = 292°K

T2 = 37 + 273 = 310°K

2.- Use the combined gas law to solve this problem

                  P1V1/T1  = P2V2/T2

-Solve for V2

                  V2 = P1V1T2 / T1P2

-Substitution

                  V2 = (783 x 4.40 x 310) / (292 x 735)

-Simplification

                 V2 = 1068012 / 214620

-Result

                 V2 = 4.97 l
