What three factors can speed up the rate of something dissolving?
Three factors that speed up the rate of dissolution are increased temperature, increased surface area, and stirring the mixture.
What are signs that an volcano is going to occur?
increased seismic activity in the area, swelling of the magma dome (in andesite volcanoes), increase in surface temperature.
What is the temperature of ice surface?
Solidification of water depends on both temperature and pressure. Experimental phase diagrams are available in any text book on the subject. For a given pressure (in most circumstances) once the temperature is below the solidification point, reducing the temperature generally will not change its state.
What do concentration surface area and temperature have in common?
Concentration, surface area, and temperature all affect the rate of chemical reactions. Increasing concentration increases the number of reactant particles colliding, larger surface area allows for more contact between reactants, and higher temperature provides more energy for particles to react.
What are the various factors which influence the evaporation of a liquid?
Factors influencing the evaporation of a liquid include temperature, surface area exposed, humidity of the surrounding air, and the presence of air movement (wind). Higher temperatures, larger surface areas, lower humidity, and increased air movement all accelerate evaporation.
The rate at which a solute dissolves is increased when it is?
It is increased by applied energy, stirring, temperature, more surface area...
What is the effect of increase of temperature on surface tension?
An increase in temperature typically decreases surface tension in liquids. This is because higher temperature leads to increased molecular motion, which weakens the intermolecular forces responsible for surface tension.
Why is the temperature to freeze the surface of ocean water lower than the temperature needed to freeze the surface of water like Lake Superior?
The ocean water has a high amount of dissolved salts.
Why would surface water in the North sea be more likely to contain a high percentage of dissolved gases than the surface water in the Caribbean?
Surface water in the North Sea would be more likely to contain a high percentage of dissolved gases due to the colder temperature and higher levels of phytoplankton productivity leading to increased photosynthesis and subsequent gas exchange. In contrast, the warmer surface waters of the Caribbean have lower gas solubility and lower levels of phytoplankton productivity, resulting in lower levels of dissolved gases.
What is the surface temperature of earth in degrees Fahrenheit and celsius?
The surface temperature of the earth can range between -89.2 deg C (Vostok Station at the Russian Research base in the Antarctic) and 56.7 dec C (Death Valley, USA). So a single measure of the surface temperature for the whole planet is a bit absurd.
What factors can affect the rate of solvation?
Factors that can affect the rate of solvation include the nature of the solute and solvent, temperature, pressure, and the surface area of the solute particles. Additionally, the presence of impurities, stirring or agitation, and the polarity of the solute and solvent can also impact the rate of solvation.
What is earth surface temperature?
At Vostok Station in the Antarctic, located at the 'pole of inaccessibility' the daily mean is about -55oC. This spot, farthest from the coast of Antarctica, also has the record for the lowest surface temperature. But where you and I live, the mean surface temperature is likely to be a few degrees C. The highest mean is either the Afar depression in Africa, or Death Valley in the USA.
What is the Antarctic surface made of?
Ninety-eight percent of the Antarctic continent is covered by an ice sheet.
What will have made the water evaporate?
The cause is the increased movement of water molecules near the surface, caused by a higher temperature.
What happens to condensation temperatures if the pressure is increased?
humdidity and the temperature differental between the air and the surface on which the condensation collects.
What affects the rate of a reaction?
The rate of a reaction increases if: · The temperature is increased · The concentration of a dissolved reactant is increased · The pressure of a reacting gas is increased · Solid reactants are broken into smaller pieces · A catalyst is used
Name 1 negative effect of deforestation?
# Loss of habitat # Increased erosion # Loss of plant & animal diversity # Increased surface temperature # Higher rate of evaporation
