- Explain why evaporation leads to cooling of the liquid.arrow_forwardWhy do liquids have a vapor pressure? Do all liquids have vapor pressures? Explain. Do solids exhibit vapor pressure? Explain. How does vapor pressure change with changing temperature? Explain.arrow_forwardWhat term is used to describe a substance that readily evaporates at room temperature because of a high vapor pressure?arrow_forward
- ook at Fig. 14.2. Why doesn't temperature increase continuously ever time? That is, why does the temperature stay constanl for periods of time?arrow_forwardA special vessel (see Fig. 10.45) contains ice and supercooled water (both at 10C) connected by vapor space. Describe what happens to the amounts of ice and water as time passes.arrow_forwardIdentify two common observations indicating some solids, such as dry ice and mothballs, have vapor pressures sufficient to sublime?arrow_forward
- Identify two common observations indicating some liquids have sufficient vapor pressures to noticeably evaporate?arrow_forwardDefine the following and give an example of each: (a) dispersion force (b) dipole-dipole attraction (c) hydrogen bondarrow_forwardIn each of the following groups of substances, pick the one that has the given property. Justify your answer. a. highest boiling point: HBr, Kr, or Cl2 b. highest freezing point: H2O, NaCl, or HF c. lowest vapor pressure at 25C: Cl2, Br2, or I2 d. lowest freezing point: N2, CO, or CO2 e. lowest boiling point: CH4, CH3CH3, or CH3CH2CH3 f. highest boiling point: HF, HCl, or HBr g.arrow_forward
