Answer: The correct answer is force of gravity.

Explanation:

Gravity is the force with which one body attracts the other body.

It goes down a hill with the increase in the kinetic energy. The kinetic energy is due to the motion of a wagon.

At the hill the gravity is lesser in comparison to the gravity on the surface of the earth.

When a wagon rolls down a hill it speeds up. Here, the earth attracts the wagon with the force of gravity. It accelerates down a hill with an acceleration due to gravity.

A process with a negative change in enthalpy and a negative change in entropy will generally be:________

A process with a negative change in enthalpy and a negative change in entropy will generally be: <u>spontaneous</u>.

<h3>Gibbs free energy:</h3>

Since the Gibbs free energy is a parameter that tells us whether a chemical reaction is spontaneous (Gibbs free energy less than 0) or nonspontaneous (Gibbs free energy greater than 0) in this situation, we can describe it mathematically as:

                                      ΔG = ΔH - TΔS

Therefore, any process with a negative change in enthalpy and a positive change in entropy will be spontaneous. If the enthalpy and the entropy are both negative, the subtraction becomes always negative, for which the Gibbs free energy is also negative.

One of the most crucial thermodynamic functions for the characterization of a system is the Gibbs free energy. It influences results like the voltage of an electrochemical cell and the equilibrium constant for a reversible reaction, among others.

It is said that a gas fills all the space available to it. Why then doesn't the atmosphere go off into space?
Alex777 [14]
Earth has its own atmosphere. That is one reason all the water that has been on Earth has been recycled through the water cycle. It never leaves Earth’s atmosphere.
