What is specific weight of mercury?

What is specific weight of mercury?

The specific gravity of mercury is 13.56.

What is the specific weight of water at 20 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.

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 is the specific gravity of mercury in kg m3?

Calculate this pressure in SI and CGS units using the following data : Specific gravity of mercury = 13.6,Density of water = 103 kg/m3,g = 9.8 m/s2 at Calcutta .

How do I calculate specific weight?

What is the specific weight of mercury and water?

The specific weight of water at ordinary pressure and temperature is 9.81 kN/m3. The specific gravity of mercury is 13.56. Compute the density of water and the specific weight and density of mercury.

What is the value of the specific heat of water at 20 degrees C in units of joules per gram degree C?

The quantity of heat is frequently measured in units of Joules(J). Another property, the specific heat, is the heat capacity of the substance per gram of the substance. The specific heat of water is 4.18 J/g° C.

What is the physical state of water at degree Celsius and 20 degrees Celsius?

Hint: The solid state of water is ice as the liquid form of water is water and in gaseous form is vapor. These conversion forms are visible to everyone in day to day life. Hence the state of water at a temperature of -20° c is ice.

What is the density of water at 20 degrees Celsius in kg m3?

The density of Water in Room Temperature Its value at normal temperature (about 20 degree C) is 998.2 kg/m 3 .

Is mercury liquid at 20 degrees Celsius?

Most of the metals are solids under “ordinary” conditions (i.e., 25ºC, 1 atmosphere of pressure, etc.), with the exception of mercury (Hg, element 80), which solidifies at -39ºC, and is a freely-flowing liquid at room temperature.

What is the specific heat of mercury in J kg C?

The specific heat of liquid mercury is 140 J/kg. ∘ C. When 1.0 kg of solid mercury at its melting point of -39∘ C is placed in a 0.50 kg aluminum calorimeter filled with 1.2 kg of water at 20.0 ∘ C, the mercury melts and the final temperature of the combination is found to be 16.5∘ C.

Why is mercury a liquid at 25 degrees?

Liquid Elements at 25°C Mercury is the only metal that is a liquid at room temperature. It is a shiny, silver metal with a melting point of 234.3210 K ​(−38.8290 °C, ​−37.8922 °F) and boiling point of 629.88 K ​(356.73 °C, ​674.11 °F). The reason mercury is a liquid is due to relativistic effects.

What is the density mercury 13.6 g cm3?

The density of mercury is 13.6gcm−3 at 0oC and its coefficient of cubical expansion is 1.82×10−4oC−1.

What is its mercury specific gravity?

Substance	Density (g/mL)
Water	1.00
Gold	19.3
Mercury	13.6

What is the specific of mercury?

The specific gravity of mercury is 13.6.

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 specific of weigh?

The specific weight, also known as the unit weight, is the weight per unit volume of a material. A commonly used value is the specific weight of water on Earth at 4 °C (39 °F), which is 9.807 kilonewtons per cubic metre or 62.43 pounds-force per cubic foot.

What is the specific gravity of mercury if it has a density of 13.6 g mL?

Substance	Density (g/mL)
Water	1.00
Gold	19.3
Mercury	13.6

Is specific weight the same as density?

Density is defined as mass per unit volume. It has the SI unit kg m-3 or kg/m3 and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m-3). It is therefore a relative quantity with no units.
