(a)
Interpretation:
By using kinetic molecular theory, what type of energy is related to 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
- 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 has on the magnitude of 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 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.
(c)
Interpretation:
By using kinetic molecular theory, what is the general effect of cohesive forces on a system of particles has to be answered.

- A calorimeter contains 72.0g of water at 19.2C. A 141-g piece of tin is heated to 89.0C and dropped into the water. The entire system eventually reaches 25.5C. Assuming all of the energy gained by the water comes from the cooling of the tin-no energy loss to the calorimeter or the surroundings-calculate the specific heat of the tin.arrow_forwardAre changes in state physical or chemical changes? Explain. What type of forces must be overcome to melt or vaporize a substance (are these forces intramolecular or intermolecular)? Define the molar heat of fusion and molar heat of vaporization. Why is the molar heat of vaporization of water so much larger than its molar heat of fusion? Why does the boiling point of a liquid vary with altitude?arrow_forwardThe enthalpy of vaporization of water is larger than its enthalpy of fusion. Explain why.arrow_forward
