As water is cooled from 4 degrees C to 0 degrees C its density?
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
How do you compare substances to water using a mass to volume relationship?
You can compare the density, which is mass/volume. For pure water at normal atmospheric pressure this is approximately 1 gram per cm3 although in fact it is has a maximum value of 0.999 972 0 g/cm3 at 4 deg C. At 100 deg C it is 0.958 4 g/cm3 and at 0 deg C it is 0.999 839 5 g/cm3 .
Can a temperature on the celsius scale go below zero?
The Celsius or centigrade scale runs from -273 deg C to you name it. 0 deg C is the freezing point of pure water 100 deg C is the boiling point of water. 15,000,000 deg C is the core temperature of the Sun The Kelvin scale (K) uses the same units. -273 deg C = 0 deg K. 0 deg K is also known as absolute zero, the point at which no further heat energy can be extracted from a system
What is the number difference between Fahrenheit and Celsius?
There is not a constant difference. At the freezing point of water, 0 deg Celsius = 32 deg Fahrenheit - a difference of 32. At the boiling point of water = 100 deg C = 212 deg F, the difference is 180.
0 degrees c is equal to how many degrees f?
The conversion equation is F = (9/5)C + 32. To convert 0 deg. C to F, replace C with 0, and the answer is 32 deg. F, or the freezing point of water.
How temperature affect the density of water?
The density of water increases as its temperature increases from 0 deg C to 4 deg C (the anomalous expansion phase). Above 4 deg C, the density decreases with temperature.
What is the density if water is cooled fron 4 degrees celcius to 0 degrees celcius?
The density of water increases as it cools from 4 degrees Celsius to 0 degrees Celsius. At 4 degrees Celsius, the density of water is 999.972 kg/m³, and at 0 degrees Celsius the density is 999.8395 kg/m³.
What form will water be at 2 degree centigrade?
At 2 deg. C water is a mainly liquid. Some of it might 'disappear' as dry air may be humidified by the water. Ice, however is not to be expected, as pure water melts at 0 deg. C. Contamination of the water (salt) may lower this melting point. The freezing of water doesn't have to take place at 0 deg. C. Pure water can be super-cooled at temperatures as low as -40 deg. C before it freezes. Contamination by small particles helps water freezing at higher sub-zero temperatures. Agitating super-cooled water is also a means of freezing it instantly.
As water is cooled from 4 degrees C to 0 degrees C its density?
4° C is the temperature of maximum density for water. Change temperature in either direction from there -- whether you warm it or cool it -- the density decreases.
As water is cooled from 4 degrees Celsius to 0 degrees Celsius it's density is what?
As water cools from 4 degrees Celsius to 0 degrees Celsius, its density decreases. This decrease in density is due to the formation of hydrogen bonds between water molecules, causing them to arrange in a more organized structure that takes up more space, decreasing the overall density of the water.
How does the density of water change as a function of temperature?
The density of water decreases as temperature increases up to 4°C, where it reaches its maximum density. As water goes below 4°C, it starts to expand and becomes less dense. This is because water molecules form a more organized structure at lower temperatures, leading to the expansion of the substance.
Which will have the greater density water at 40 degrees Celsius or water at -20 degrees Celsius?
Water at -20 degrees Celsius; heat will expand matter, so at +40 degrees Celsius, water would have less density. * * * * * That would be true if there were no phase change. Unfortunately for the above answer, water freezes at 0 deg C and that phase change is accompanied by an expansion. As a result, water at 40 deg C is denser that water (ice) at -20 deg C.
When does water boil and freeze on the celsius scale?
At normal pressure, pure water boils at 100 deg C and freezes at 0 deg C.
How do you compare substances to water using a mass to volume relationship?

What is the physical state of water at 0 and deg celsius?
At 0 degrees Celsius, water is in a solid state, known as ice.
