What is the average density of mercury in units of kg m3?
The density of mercury is 13600 kg m^-3 .
What is the density of mercury at 25 degrees Celsius?
At 25°C and a pressure of 760 mm Hg, the density of mercury is 13.5 g/mL; water at the same temperature and pressure has a density of 1.00 g/mL.
What’s the density of mercury?
Mercury has a density of 13.5 g/mL, which is about 13.5 times denser than water (1.0 g/mL), so a small amount of mercury like this feels unexpectedly heavy.
What is the density of mercury at 20 C?
The density of mercury at 20 degree C is 13545.848 kg/m3.
Why is the density of mercury 13600 kg m3?
Density of mercury = 13600 Kgm-3. Density of water at 4oC = 1000 kg m-3. Relative density = density of substance /density of water at 40C. Relative density of mercury = 13600 Kgm-3/1000 kg m-3 = 13.6.
What is 7850 kg m3 density?
The density of steel rod is 7850 kg/m^3 , its mass is 5 kg .
How do you find density in kg m3?
- Measure the object’s mass (or weight) in kilograms.
- Measure the volume of the object in m3.
- Divide the mass by the volume.
- You will then have the density of the object in kg/m3.
- Measure the object’s mass (or weight) in kilograms.
- Measure the volume of the object in m3.
- Divide the mass by the volume.
- You will then have the density of the object in kg/m3.
What is the density of mercury 13.6 g cm3 in units of kg m3?
=13. 6×10−3×106=13. 6×103 kg/m3.
What is the density of water at 25 degrees Celsius in kg m3?
Water has a density of 997 kg/m 3 at 25 degrees Celsius. The density is defined as the mass per unit volume ratio. Pure water has a density of 1g/cm 3 or 1000kg/m 3 .
What is the density of a gas at 25 degrees Celsius?
The density of oxygen at 25∘C and 0.850 atm is 1.11 g/L. The density of a gas is directly proportional to its molecular weight. This relationship between the density and molecular weight of a gas suggests that you can use a measurement of gas density to determine molecular weight.
What is water’s density at 25 degrees Celsius?
Pure Water Density Standard UKAS ISO/IEC17025 and ISO Guide 34 certified, 0.9982g/mL 20°C, 0.9970g/mL 25°C 7732-18-5.
Why mercury density is so high?
Q: Why is Mercury so dense? Mercury is dense because its heavy iron core amounts to nearly two-thirds of the planet’s mass, more than twice the ratio of core to mass for Earth, Venus, or Mars.
What is the size and density of mercury?
Density, mass and volume The mass and volume of Mercury is only about 0.055 times that of Earth. But because Mercury’s small mass is enclosed inside of a tiny body, the planet is the second densest in the solar system, weighing in at 5.427 grams per cubic centimeter, or 98 percent of the density of our planet.
Which is denser gold or mercury?
Parts of gold sink, though because gold has a greater density than mercury does. Hence, Copper is more dense than mercury.
What is the density of heavy water at 20 C?
of electricity). For example, heavy water freezes at 3.8 °C under a pressure of 1 atm and its normal boiling point is 101.42°C; the maximum density of the saturated liquid occurs at 11.2°C. At 20°C, its density is 1.1050 kg/dm3 compared to 0.9982 kg/dm3 for H20.
What is the density of hydrogen at 20 C?
Specific volume is the inverse of density and expresses the amount of volume per unit mass. Thus, the specific volume of hydrogen gas is 191.3 ft3/lb (11.9 m3/kg) at 68 ºF (20 ºC) and 1 atm, and the specific volume of liquid hydrogen is 0.226 ft3/lb (0.014 m3/kg) at –423 ºF (–253 ºC) and 1 atm.
How do you find the density of water at 20 degrees Celsius?
In general, we say that the density of water is 1000 kg/m^3 (or 1 g/cm^3). But you’re right that it does vary a little bit with temperature. It is exactly 1000 kg/m^3 at 4 degrees Celsius. At 20 degrees Celsius it is 998.23 kg/m^3 ( or 0.99823 g/cm^3).
What is the state of water at 20 C?
Water, at a standard room temperature of 20 degrees Celsius, is a liquid.
What is the state of mercury at C?
And the temperature at which this happens is negative 38.8 degrees Celsius. So, below this temperature, mercury is a solid. And above this temperature, mercury is a liquid. The question also tells us that mercury boils at 356.7 degrees Celsius.
Is mercury liquid hot or cold?
Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
Is mercury liquid at 0 C?
Hence, mercury is the only metal which is liquid at 00C.
