(a)
Interpretation:
By using kinetic molecular theory, what type of energy is related to disruptive forces has to be answered.
Concept Introduction:
Kinetic Molecular Theory of matter says about the way of matter can change among its phases of
- 1. Matter is composed of tiny particles (atoms, molecules, or ions) that have definite and characteristic sizes that do not change.
- 2. The particles are in constant random motion and therefore possess kinetic energy.
- 3. The particles interact with one another through attractions and repulsions and therefore possess potential energy.
- 4. The kinetic energy (velocity) of the particles increases as the temperature is increased.
- 5. The particles in a system transfer energy to each other through elastic collisions.
(b)
Interpretation:
By using kinetic molecular theory, what effect does temperature have on the magnitude of cohesive forces has to be answered.
Concept Introduction:
Kinetic Molecular Theory of matter says about the way of matter can change among its phases of solid, liquid, and gas. The basic idea of this theory is about the particles (atoms, molecules, or ions) present in a substance has constant motion and are attracted or repelled by each other. The kinetic molecular theory of matter provides five statements which explain the physical behavior of the three states of matter (solids, liquids, and gases) and they are summarized as follows,
- 1. Matter is composed of tiny particles (atoms, molecules, or ions) that have definite and characteristic sizes that do not change.
- 2. The particles are in constant random motion and therefore possess kinetic energy.
- 3. The particles interact with one another through attractions and repulsions and therefore possess potential energy.
- 4. The kinetic energy (velocity) of the particles increases as the temperature is increased.
- 5. The particles in a system transfer energy to each other through elastic collisions.

Interpretation:
By using kinetic molecular theory, what is the general effect of disruptive forces on a system of particles has to be answered.

- In what ways is water unique? What about the water molecule causes the unique properties of water?arrow_forwardThe enthalpy of vaporization of water is larger than its enthalpy of fusion. Explain why.arrow_forwardWhat happens to the temperature of the liquid in a cup of water as some of the water evaporates? A. The temperature increases because there are fewer molecules to share energy between. B. The temperature decreases because new molecular bonds form. C. The temperature decreases because the most energetic molecules escape. D. The temperature increases because the vapor pressure increases.arrow_forward
- What is a chemical bond? How is it different from intermolecular forces of attraction?arrow_forwardWhat is the difference between a chemical and physical change? What is the difference between an intermolecular force and an intramolecular force? Explain why it takes more energy to break an intramolecular force than it does an intermolecular force. Define viscosity. Describe what surface tension is and how you know that water has a higher surface tension than alcohol. If a substance has a high viscosity, then it has strong intermolecular forces. For example, in the investigation we did, we found that room-temperature corn syrup had stronger intermolecular forces/higher viscosity than the hot corn syrup because it took longer for it to pour out of the beaker. Describe cohesion and adhesion and how they relate to your everyday life. Substances with high boiling, melting, and freezing points have stronger intermolecular forces. Four types of intermolecular forces: dispersion forces, hydrogen bonds (H-O, H-F, H-N), ion-dipole, dipole-dipole Which intermolecular force exists…arrow_forwardIt is an attractive forces between polar molecules. 7. a Dipole-dipole b. Dispersion 8. Why the hydrogen bond is considered a "special" dipole-dipole interaction? It is polar C. Ion-dipole d. Intermolecular Because of the similarity in electronegativity d. Bonded to a very electron negative atom such as N, F and O C. a. b. It has covalent bonds 9. These intermolecular forces as a group are referred to as a. Intermolecular forces C. Solid forces b. London forces d. Van der Waals forcesarrow_forward
