Water is at a minimum temperature when it is frozen, which is 0 degrees Celsius or 32 degrees Fahrenheit
From my high school memory, I recalled that water has minimum volume when at 4 degrees Celcius. This is why it is able to penetrate rocks as it is cooling and then crack them apart once it freezes again.
Then I found this site http://www.simetric.co.uk/si_water.htm
which states
At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml,
1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft
and
When water freezes it expands rapidly adding about 9 % by volume. Fresh water has a maximum density at around 4° Celsius. Water is the only substance where the maximum density does not occur when solidified. As ice is lighter than water, it floats.
What else can I help you with?
When water is warmed from its freezing temperature to its temperature of maximum density it?
expands in volume and decreases in density. At the point of maximum density, water molecules are arranged in a hexagonal structure, causing the water to be most compact. Beyond this point, as water continues to warm, it expands and becomes less dense.
What has a effect on water density?
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
Why is the temperature 4'C mentioned in defining density of water in CGS system?
When water in liquid form is cooled, the molecules come closer and closer together, increasing its density to a maximum at 4 degrees Celsius. (Further cooling slightly decreases the density until Zero dgrees Celsius. At that temperature, water molecules start sticking together in rings of six molecules. These take up more room than molecules simply bunched together, so ice is less dense than liquid water.)
How to find the density of water at a certain temperature?
To find the density of water at a specific temperature, you can use a reference table or formula that provides the density of water at different temperatures. Alternatively, you can measure the mass and volume of a sample of water at that temperature and use the formula density mass/volume to calculate the density.
What is the formula to solve the density of water for change in temperature?
The formula to calculate the density of water for a change in temperature is: Density = Density at reference temperature / [1 - β (T - T_ref)], where β is the volumetric thermal expansion coefficient of water, T is the temperature, and T_ref is the reference temperature.
What temperature does pure water reach maximum density?
Pure water reaches its maximum density at a temperature of approximately 4 degrees Celsius. This is why water typically contracts as it cools below this temperature, but expands as it freezes into ice.
What degree Celsius does water reach maximum density?
Water reaches maximum density at 4 degrees Celsius
The Temperature at which water possesses maximum density is?
The temperature at which water possesses maximum density is 4 degrees Celsius. At this temperature, water molecules are packed closely together, decreasing the volume per molecule and increasing the density.
When is water's density at its greatest?
The maximum density of water occurs at a temperature of 4°C
What is the maximum temperature that boiling water can reach?
The maximum temperature that boiling water can reach is 212 degrees Fahrenheit (100 degrees Celsius) at standard atmospheric pressure.
What is the temperature of maximum density for sea water?
The temperature of maximum density for seawater is approximately 3.98 degrees Celsius. This means that at this temperature, seawater has its highest density, which is important for ocean circulation and thermohaline processes.
Why does the temperature of water stop rising at 23 degrees centigrade?
At 23 degrees Celsius, water reaches its maximum density. As the temperature of water increases beyond this point, its density begins to decrease, causing colder water to rise to the surface. This phenomenon is known as the temperature of maximum density.
At what temperature does luquid water have its maximum density?
Liquid water has its maximum density at 4 degrees Celsius. At this temperature, water molecules are densely packed, causing the water to be the most compact, which is why ice forms on the surface of bodies of water at this temperature.
At what temperature does maximum density occur?
The maximum density of water occurs at 4 degrees Celsius (39.2 degrees Fahrenheit). At this temperature, water molecules are arranged in a way that allows for the highest density before expanding and becoming less dense as it freezes into ice.
What happens to a sample water when it is heated between 4c and 100c?
Its temperature rises. As 40C is the temperature where water has its maximum density, then the density will drop as well
At what temperature does fresh water have the highest density?
The maximum density of ultrapure water (0,9999720 g/cm3) is at 3,98 0C.
When water is warmed from its freezing temperature to its temperature of maximum density it?
expands in volume and decreases in density. At the point of maximum density, water molecules are arranged in a hexagonal structure, causing the water to be most compact. Beyond this point, as water continues to warm, it expands and becomes less dense.
