An endothermic reaction requires
More energy than it produces; it will consume heat rather than produce heat
With endothermic reactions, solubility is
Increased with increased temperature; the additional energy (heat) drives greater dissolving
Most reactions of solids dissolving in liquids are
Endothermic
What is exothermic mean?
Energy is released in excess of the energy required to break the bond of the solute
Pressure & solubility
No correlation/influence
What is the latent heat of vaporization?
The energy needed to transform a given amount of liquid into a gas & is measured in kilojoules
The temperature at which the bulk of a liquid at a given pressure is converted to a vapor is the
Boiling point
The temperature of a liquid will not
Raise above its boiling point; instead, the additional heat energy transforms the liquid into gas
The rate of vaporization depends only on the
Temperature, the vapor pressure of the liquid, & the partial pressure of the vapor above the evaporating liquid
In a closed container,
Equilibrium will be achieved between molecules in the gaseous phase & those in the liquid phase
As gas molecules escape the liquid, they
Exert a pressure known as vapor pressure. measured in millimeters of mercury
All liquids that have high vapor pressures at room temperature are known as
Volatile liquids
Vapor pressure & boiling points are
Inversely related
Different liquids exert different vapor pressures at a
Given temperature
If a high vapor pressure volatile anesthetic is placed inside a calibrated low vapor pressure,
The output will be higher
A volatile with a lower vapor pressure placed in a calibrated higher, the output will be
Lower
