When heating a substance, a phase change will start to occur when the kinetic energy of the particles is _____________ the attractive forces between the particles. Question 8 options: A. great enough to combine
B. low enough to combine
C. low enough to overcome
D. equal to
E. great enough to overcome

Answers

Answer 1
Answer:

Answer: E. great enough to overcome.

Explanation: The three phases of the substances are solid, liquid and gas.

When a substance is heated, that is the molecules gain kinetic energy as kinetic energy is directly proportional to temperature.

The phase change will take place only when kinetic energy will be greater than the inter molecular forces as the molecules have to move in more random motion.

For example: Solid with high inter molecular forces are heated to convert it into liquid state only when kinetic energy will overcome the inter molecular forces of attraction.
Answer 2
Answer: Your answer is great enough to overcome :)

Which court would you go to if you wanted to declare bankruptcy?A.
Civil court
B.
U.S. Court of Appeals
C.
Supreme Court
D.
U.S. District Court

Answers

Civil court  would you go to if you wanted to declare bankruptcy. The correct option is A.

Thus, According to the United States Bankruptcy Code, bankruptcy proceedings are typically filed in a federal bankruptcy court.

The federal court system includes these courts, which deal with Chapter 7, Chapter 11, and Chapter 13 bankruptcy cases.

The additional alternatives (U.S. Court of Appeals, Supreme Court, and U.S. District Court) are not the main courts where bankruptcy cases are generally filed.

Thus, Civil court  would you go to if you wanted to declare bankruptcy. The correct option is A.

A gas is heated from 298 K to 367 K while its volume changes from 2.5 L to 3.9 L. If the initial pressure of the gas is 1.1 atm, what is the final pressure of the gas?

Answers

This problem can be solved using one of the different gas laws, which is shown below:

PV/T

Given:

P1 = 1.1 atm
V1 = 2.5 L
T1 = 298 K

P2 = ?
V2 = 3.9 L
T2 = 367 K

Substituting the given:

P1V1/T1 = P2V2/T2

(1.1 * 2.5)/298 = (P2 * 3.9)/367
P2 = 0.868 atm

The answer is 0.87 atm

Is newton third law accurate for electric forces?

Answers

An object with greater charge will exert a greater force on an object than an object with smaller charge would. However, if you consider two charges that exert a force on each other, regardless of the magnitude of charge, both charges will exert an equal force on each other because of Newton's third law.
