it all depends on what Temperature is acting upon.  If your talking about a solid, no, not really, if it does, it is negligible.  However, Temp. does affect the density of liquids, most liquids become more dense as temp. get colder, and less dense if the temp gets higher.  If you are talking about gasses, then the temp will affect both volume and density. think of a balloon. If you put a balloon outside in the winter, it will become smaller.  This is because the density of the air inside goes up and the volume goes down.... \nThe formula to determine what happens with a gas is PV=nRT, whereby P=the atmospheric pressure, V=volume, n= the #of moles of a gas R=is the ideal gas constant and T=temp... hope that helps.

The density of the fluid and the density of the object.

In addition to the fact that at 4 degrees celcius, water has an absolute density of EXACTLY 1 g/cc, at 0 degrees, it is in equilibrium with its solid phase (ice) which has a density of LESS than 1 g/cc due to its open cage like crystal structure. So, its exact density at 0 degrees is impossible to standardise.

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 is measured by weight per unit of volume, such as the density of water is 62.4 pounds per cubic foot.\n\nViscosity is a measurement of the rate at which a liquid flows or more accurately, its resistance to flowing. Water has low viscosity, honey has high viscosity.

the most common formulas involving mass and density are:\n\nD=M/V     (D is density, M is mass, and V is volume.   \n                the "/" sign means division)\n\nyou can use this equation to find other equations.\n\nVD=M        (Volume times Density equals Mass)\n\nM/D=V        (Mass divided by Density equals Volume)\n\n\nas far as definitions for mass and density, mass is how much matter is contained in an object and density is the ratio of the amount of matter to the amount of space it takes up.

density=__g/ml   that means density equals __grams per millileter

look at column 7.  all of the densities appear there in grams/cm3.\n\nhttp://www.science.co.il/PTelements.asp

The density can be assumed to be 1.0 g/ml.  \n\nSo you have 25 ml x 1.0 g/ml = 25 g H2O\n\nThe molar mass of water is 18 g/mol, so you have:\n\n25 g H2O/18 g H2O/mol H2O = 1.4 mol H2O

the weight will be according 2 density of the material \n\nfor example for water 1  liter wighs 1 kg

density has to do with the relationship between mass and volume. Water has a density of 1. As long as the mass stays in the same relationship with the volume of water, it has the same density.

I'll agree that you need help.  Density is mass/vol.  You've given the density, you need another value to calculate the remaining value.

well the formula is the square root of 3kT/m  where k is the boltzman constant(1.38066 x 10^-23 J/K) T is in Kelvin so you would have to convert(just add 273 to the temp in Celcius) so your T is 290K and m is the mass. the mass can be found using the density of water(1000 kg/m3) the formula for density is d=m/V and V can be found by using the volume of a sphere, 4/3(pi)r^3 oh, and don't forget to convert the nanometers into meters, then cut the diameter in half for radius.\nusing this information to get you started, you should be able to do it yourself. so you should try it first before reading further :) im sure you were familiar with all of those formulas, you just need to remember to think of things all at once so you can put them together.\n\nok, so we start with the rms velocity formula. first problem is that we need mass. ok, lets solve for mass using density. oh right, we need volume, ok, lets solve for volume then:\nwe need to make the diameter into meters, so thats 1.0 x 10^-8 meters. now we cut this in half to get the radius(r) so that's 5.0 x 10^-9.\nV=(4/3)(pi)r^3\nV=(4/3)(3.14159)(5 x 10^-9)^3\nV=5.236 x 10^-25 m^3\nnow we have volume, so using the density of water(1000 kg/m3), we can solve for mass:\nd=m/V\n1000=m/(5.236 x 10^-25)\nm=5.236 x 10^-22 kg\nok, now we have mass, so we can use our original rms velocity formula and solve for velocity. *sigh* finally.\n\nv(rms)= sqrt[3kT/m]\nv(rms)= sqrt[3(1.38066 x 10^-23)(290)/(5.236 x 10^-22)]\nv(rms)= 22.94 m/s\n\ni would check my math if i were you though, i tend to make stupid calculator errors. the concepts are there though :p

Use:\n\npressure = density x height x g\nwhere g = 980 cm/s^2\n\nfor each liquid.  the answer (in dynes) will be the sum of the two pressures.

Finding the density of a gas requires information on pressure, and temperature.  d=pM/RT where d is density, p=pressure in atm, M is molar mass, R is the gas constant, and T is temperature in kelvin.  For a liquid the only factors to calculate density are mass, volume and temperature.  d=m/V...at a given temperature.  For solids the mass and volume are only needed.

Density is mass over volume.\n\np = m/v\n1.74 = m/43.5\n1.74 * 43.5 = 75.69 (mass)\n\n75.69 g
