At what temperature is water most dense? And what is the density of water at this temperature?(g/cm3 if can)?

The density of water goes down when it is frozen and down when it is heated, so I would say just above freezing.  According to the website, about 4 degrees C.  The density of water at this temperature is 1.000g/cm3

Fluid Pressure= weight density x (times) depth\n\nFl. p.= 10,000 kg/m^3(thats the weight density of water) x 15 m\n\nFl. p.= 150,000 m^2 (because one m cancels)\nHope this helps!

Density and phase 0.626 g/cm3, liquid

I'm not sure. But the volume of a sphere is (4/3)(pi)(r)^(3). \n2) You know that the diameter is double the radius. So your radius is 1.\n3) Then, your volume is (4/3)(pi). \n4)Density=(mass/Volume)\n5)Density of water is 1.00 mL=1.00g/m^3\n6)MASS=(Density)(Volume)=((1.0g/m^3)(4/3)pi). Note that cubic meters cancel. The mass is (4/3)pi grams.\n\nHope I helped.

Density is a factor that cannot be changed except by physical changes such as phase changes. 1 Liter of water at 5°C will have the same density as 1 Liter of water at 90°C, and because density is g/cm^3, the density of 1, 10, or 100 milliliters(a unit of liquid volume) of water is the same, because water weighs 1 gram per millilter, so 1/1=1density),\n10g/10ml=1, and 100g/100ml=1

MY GOD!  Don't answer if you don't have a clue.\nA) False - water is exactly 1g/cm3\nB) False - ice floats, thus less dense\nC) False - Water is made of two elements (Hydrogen and Oxygen), thus it cannot be an element itself.\nD) True - The mass of water does not change when it is frozen, melted or heated into steam.  It is still H2O.  No atoms were split or made!\nE) False

The density of water is 1 gram/cubic centimeter.\nThe density of ice, due to hydrogen bonding, is .931\ngrams/cubic centimeter. Therefore the less dense mass\nof ice is "lighter" than the more dense mass that is water.\n\nWhy is this important? because if ice did find some sinister\nway to be heavier than water, i would not be able to crunch\nice when i drink my favorite beverage... that is until the\nbeverage is all gone, and by that time, i'm just out of the\nmood.

I know that water is most dense at 4 degress celsius

In part, specific gravity can be measured with a hydrometer.  You establish a range that the liquid displaces and let it bob until it comes to equalibrium.  This test can be measured at any temperature.  \n\nHowever, mass density is done in a container that is kept at a constant temprature.  The math is easy once the measurments are taken, but there is more time involved in setting up the test and bringing the whole thing to equalibrum

1 cm3 of water equals 1 gram of water.\n1 gram of water equals 0.001 kilograms of water\nThus 455 cm3 = 0.455 kg (unlike the first answer you got)

The density of blood can vary by a number of variablies, including if yo uare standing or sitting when you do the calculation. However, the average density of human blood  is about 1060 kg/m3. For plasma (no blood cells) alone it is  1025 kg/m3, with the average density of he circulating blood cells  as about 1125 kg/m3.\n\nFor reference, the density of water at human body temperature is approximately 0.9922 kg/m3.

Looks like this is your homework. anyway, i'll only answer two of your questions.\n\n1. the density of water is almost 1 g/mL. and 1 liter = 1000 mL. hence the mass of 1 liter of water is 1000 g.\n\n2. since 1 liter of water is 1000 g or 1.00 kg, its weight is 1.00 * 9.8 = 9.80 N

It's 277K.\nWater density is greatest at 4 degrees Celsius (O degrees Celsius = 273K, so 4 degrees Celsius = 277K).\nWhen the temperature decreases to 0 Celsius, the density of water decreases to 0.999 g/cm^3 and the volume increases about 10%.\nThat's why ice floats on rivers - because at 0 degrees Celsius it has lower density than water!\n\nGreetings from Poland!

Density is a measure of mass per volume. Same amount of water; sugar water is denser. Weigh; salt is NaCl, sugar is a more complex and heavier molecule. Formula for glucose. C6 H12 O6. Denser.\n\nNo. sugar water is denser than salt water. Period.

at 4degree c water has highest density but if we increase or decrease the temperature water density start decreasing . when we decrease temperature of water water molecules start  attaching with eachother by inter moleculer hydrogen bonds  one molecule of water associates 4 other molecules by this bond ,forming a big  molecule  but all the molecules of water in  this  big molecule is not well packed and a lot of space is left in side the big molecule we call it cavity and this cavity increase the volume but not the mass . so density decrease means volume increases,\n  but if we change the ice into water then this intermolecular hb breaks and  free water molecules start filling this cavity and hence density increases upto 4degree c, but if we further raise temperature the thermal expansion of the water happens and it causes density decreasing ie volume increement

For water, it's easy: 1mL=1g. For everything else, you need to know the density. Density is g/mL. So, if you have 3g of something that has a density of 6g/mL, you have 0.5mL of stuff.

DENSITY is the key.\n\nRemember, an aircraft carrier will float in water because it is less dense than the water.  To calculate density, divide mass - kilograms (m) by volume - cubic meters (v).\n\nPure water at 25 degrees Centigrade has a density of 998 kg/m^3 so any object with a density lower than this would float.  Higher would sink.\n\nInteresting note:  If you could find a body of water large enough, the planet Saturn would actually float in it since it is less dense.
