When a substance freezes does its density change?
Yes. When frozen, water expands becoming less dense. (That's why ice floats in water ... even in ice-cold water.)
How does water in the spaces of a limestone cause physical weathering of the limestone?
Water in the spaces of limestone can cause physical weathering through a process called freeze-thaw. When water seeps into the cracks and pores of the limestone, it freezes and expands upon freezing, exerting pressure on the surrounding rock. This expansion and contraction cycle weakens the limestone, causing it to crack and break apart over time.
Why does saltwater have a lower freezing point than fresh water?
the salt molecules interfere with the intermolecular forces and hydrogen bonds of the water molecules.
How many Fahrenheits are in a degree?
You are mixing apples and oranges. A degree is a unit of measure. How big the unit is depends upon the scale. Fahreheit is a scale of temperature measurement. There are 180 degrees between boiling and freezing temperature of water. Celsius is a scale of temperature measurement. There are 100 degrees between boiling and freezing termperature of water.
What is the freezing point of mixture alkohol and water?
Freezing point would depend upon proportion of alcohol and water .
What is forest wedging?
forest wedging is example of physical weathering process which water expands upon freezing by 10%
What are the 5 characterics of Water?
odorless tasteless liquid expands upon freezing freezing point 0° C boiling point 100° C maximum density at 4° C
If a substance contracts when it freezes?
The vast majority of substances contract upon freezing. The notable exception is water for which the expansion upon freezing has an enormous impact on the nature of the Earth. Most substances contract and become denser upon freezing, but water expands and becomes less dense below about 4 ºC. It is this expansion that causes pipes and bottles to crack when their contents freeze, and rocks to split open when water freezes in their crevices. Icebergs and blocks of ice float in water because they are less dense than the water from which they were frozen. See related links below for more information.
When water is different from most substances in that is expands upon changing from liquid to a solid true or false?
TRUE!
When a substance freezes does its density change?
Yes. When frozen, water expands becoming less dense. (That's why ice floats in water ... even in ice-cold water.)
What is a freezing nucleus?
a small particle upon which water molecules can collect in solid form.
Do Most liquids do not expand upon freezing?
No only water it's the odd one.
Why is water the only substance that expands when frozen?
Nope. Silicon(Si), Gallium(Ga), Antimony(Sb), Bismuth(Bi) and acetic acid(CH3COOH, vinegar) all expand on freezing as well. Moreover, silicon expands more than water on freezing (10% compared to waters 8%). The trick to this is that any substance with an open tetrahedral molecular structure will also expand upon freezing. (Perhaps phosphorus oxide(s))
If Celsius is based upon water's melting point 0 degrees Celsius and water's boiling point 100 degrees Celsius what is Fahrenheit based upon?
In Fahrenheit, 32°F is the freezing point of the water and the boiling point is 212°F. Fahrenheit for unknown reasons calibrated his scale so that 0 was the freezing point of salt water and 100 was the internal temperature in his mouth.
What does liquids become when they freeze?
Liquids become solids upon freezing. Most solids contract when they freeze. The expansion of water when it becomes ice is an unusual property.
How far mercury expands when heated?
It depend upon the temperature how much you heat it
What type of thermometer is used in the metric system?
If you mean "what temperature scale" it is Celsius (C). The scale is based upon the freezing and boiling points of pure water at sea level. Water freezes at 0 C and boils at 100 C. It is named after Swedish astronomer Anders Celsius.
