(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_forward1. Explanation of properties of solids, liquids and gas by using the kinetic molecular model. 2. Differences of Intermolecular forces (London Dispersion Forces, dipole-dipole Forces, Ion-Dipole Forces, and Hydrogen Bond) 3. In medical industry, Medical devices use adhesives as one example of application of Intermolecular Forces of Attraction. Adhesives are used extensively in th medical world, from simple plasters to advanced medical applications. Adhesives are integral to the production of paper tissues and nappies, allow tablets to be protected from the effects of moisture and allow wounds to be dressed. Trans dermal patches, such as nicotine patch, permit a controlled delivery of nicotine into the bloodstream to help smokers quit. What are other line of work that applies the Intermolecular forces of Attraction. At least one example and its use in the certain field of work. 4. Prediction of the type of Intermolecular forces that will be formed with the same kind of (a-c) and…arrow_forward
- What 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_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_forward1. How does temperature affect pressure? 2. At what approximate temperature did water become a liquid? A gas? 3. Why do you think water requires such a higher temperature to raise the pressure than neon? 4. How does volume affect temperature and pressure? 5. What conditions would produce the highest pressure? 6. How does the behavior of the particles determine the properties of the state of matter?arrow_forward
