Why is the temperature needed to freeze the ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
Dissolved salts in water contribute to a decrease of the freezing point.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
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 provides the force that causes magma to erupt to the surface?
Magma is propelled to the surface by temperature differences, which cause convection currents. The temperature differences result from radioactive elements within the mantle.
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 factors can affect the rate of solvation?
Factors that effect the solvation rate include temperature, concentration, surface area, concentration of solvent, and stirring.
The rate at which a solute dissolves is increased when it is?
It is increased by applied energy, stirring, temperature, more surface area...
During the 20th century earth's average surface temperature has?
Increased
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.
How has the Earth surface temperature increased over the past 100 years?
Due to the phenomenon known as global warming, the surface temperature of the earth is increasing every year. It is warming in some areas more than others and over the last century, the temperature has increased an average of 13 degrees.
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
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.
Effect of impurities on surface tension of liqiud?
yes The presence of impurities either on the surface or dissolved in it, affect surface tension of the liquid. Highly soluble substances increase the surface tension of water, whereas sparingly soluble substances reduce the surface tension of water. The surface tension of a liquid decreases with increase in temperature. The surface tension of a liquid becomes zero at its boiling point and vanishes at critical temperature.
Why is the temperature needed to freeze the ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
Dissolved salts in water contribute to a decrease of the freezing point.
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 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.
