An unscientific device for locating oil or minerals; a divining rod.
Answer:
number of plants that grow in the ocean
Explanation:
<em>The dependent variable would be the number of plants that grow in the ocean.</em>
The dependent variable is the actual variable being measured in an experiment. The value of dependent variables is directly affected by another variable in an experiment - the independent variable. The latter is the manipulatable variable that is directly inputted during experiments.
In the illustration, the main aim of the experiment is to determine how CO2 levels in ocean water affect the number of plants that can grow in the ocean. The manipulatable input variable would be the CO2 while the outcome variable - the dependent variable - would be t<u>he number of plants that grow in the ocean.</u>
<u>Substances in order of increasing vapor pressure at a given temperature is </u><u>SF4 < SF6 < SiH4</u>
- The substance with the lowest vapor pressure will also have the greatest boiling point.
- A liquid attribute associated with evaporation is vapor pressure.
- The distribution of kinetic energy among the molecules in a liquid (or any substance) is influenced by the system's temperature.
<h3>How do you determine vapor pressure?</h3>
- Vapor pressure in chemistry is the force that an evaporating substance exerts against the walls of a sealed container (converts to a gas).
- Use the Clausius-Clapeyron equation to determine the vapor pressure at a specific temperature: ln(P1/P2) = (Hvap/R)((1/T2) - (1/T1)
Which has highest vapor pressure?
- At the normal boiling point of a liquid, the vapor pressure is equal to the standard atmospheric pressure defined as 1 atmosphere, 760 Torr, 101.325 kPa, or 14.69595 psi.
- For example, at any given temperature, methyl chloride has the highest vapor pressure of any of the liquids in the chart.
