Concept explainers
(a)
Interpretation:
The given statement, ‘there are strong intermolecular forces of attraction between liquid molecules and also, the liquid has a low surface tension’ is correct or not, is to be identified.
(b)
Interpretation:
The given statement that, ‘surface tension increases, when the temperature is increased’ is correct or not, is to be identified.
(c)
Interpretation:
The given statement that, ‘stronger the intermolecular forces, lower the viscosity of the liquid’ is correct or not, is to be identified.
(d)
Interpretation:
The given statement that, ‘viscosity of a liquid increases on increasing the temperature’ is correct or not, is to be identified.
(e)
Interpretation:
The given statement that, ‘a rise in the water level in a capillary is due to the attractive forces between the water molecules and the molecules of the glass’ is correct or not, is to be identified.

EBK INTRODUCTION TO CHEMISTRY
- Explain why evaporation leads to cooling of the liquid.arrow_forward8.45 Describe how interactions between molecules affect the vapor pressure of a liquid.arrow_forwardCooking oil floats on top of water. From this observation, what conclusions can you draw regarding the polarity or hydrogen-bonding ability of molecules found in cooking oil?arrow_forward
- What types of liquids typically form amorphous solids?arrow_forwardDescribe the behavior of a liquid and its vapor in a closed vessel as the temperature increases.arrow_forwardConsider the following data for xenon: Triple point: 121C, 280 torr Normal melting point: 112C Normal boiling point: 107C Which is more dense, Xe(s) or Xe(l)? How do the melting point and boiling point of xenon depend on pressure?arrow_forward
- A common prank on college campuses is to switch the salt and sugar on dining hall tables. which is usually easy because the substances look so much alike. Yet, despite the similarity in their appearance, these two substances differ greatly in their properties because one is a molecular solid and the other is an ionic solid. How do the properties differ and why?arrow_forwardAn amorphous solid can sometimes be converted to a crystalline solid by a process called annealing. Annealing consists of heating the substance to a temperature just below the melting point of the crystalline form and then cooling it slowly. Explain why this process helps produce a crystalline solid.arrow_forwardWhat feature characterizes the dynamic equilibrium between a liquid and its vapor in a closed container?arrow_forward
- What term is used to describe a substance that readily evaporates at room temperature because of a high vapor pressure?arrow_forward8.48 Why must the vapor pressure of a substance be measured only after dynamic equilibrium is established?arrow_forwardRubidium chloride has the sodium chloride structure at normal pressures but assumes the cesium chloride structure at high pressures. (See Exercise 69.) What ratio of densities is expected for these two forms? Does this change in structure make sense on the basis of simple models? The ionic radius is 148 pm for Rb+ and 181 pm for CI.arrow_forward
