A gas has a pressure of 690 mmHg at 40 degrees Celsius. What is the temperature at standard pressure? Calculate the density, in grams per liter, of a gas at STP if 3.16 L of the gas at 28.5 Celsius and 734.2 mmHg weighs 0.269 g. If a balloon is...
What is the density of liquid water at 25 degrees Celsius in units of kg/m{eq}^3 {/eq}?Density:Density is a measure of how tightly matter is packed, and it explores the relationship between a certain substance and its volume. In most substances, their density varies w...
Calculate the saturation vapor pressure at given temperature TT using the formula: p1=6.1078⋅107.5TT+237.3p1=6.1078⋅10T+237.37.5T where TT is measured in degrees Celsius. Saturation vapor pressure is the vapor pressure at 100% relative humidity (our calculator uses a more accurate, but ...
The density of mercury is {eq}\rm 13600 \ kg/m^3 {/eq} at 0 degree Celsius. What would be its density at 20 degree Celsius? {eq}\rm (\beta = 0.95 \times 10^{-3} (^{\circ}C)^{-1}) {/eq} Volume expansion We have ...
Under "standard" conditions of 0 degrees Celsius and 1 atmosphere of pressure, carbon dioxide exhibits a density of 0.001977 g/mL. This value is slightly greater than that of air — 0.001239 g/mL — under the same conditions. Solid CO2 ...
- The density of water is usually taken at a specific temperature, commonly at 4 degrees Celsius, where it is at its maximum density. 4. Mathematical Representation: - The formula for relative density can be expressed as: Relative Density=Density of the substance(ρsubstance)Density of water(...
Perhaps the most important characteristic of the asthenosphere is its temperature. It is temperature, not depth, that marks the boundary between the lithosphere and asthenosphere. That boundary begins when the temperature reaches 1300 degrees Celsius. At this temperature, rock approaches its melting poin...
A local Maasai porter accidentally fell into an active lava flow at temperatures of 500 degrees Celsius (932 degrees Fahrenheit) but managed to pull himself free. However, he sustained significant burns on both legs and one arm. One of the factors that may have contributed to his survival is...
2. Increase the ground temperature: After covering the ground cloth, the ground cloth can block the heat dissipation of the soil and increase the low temperature by 3~4 degrees Celsius. 3. Keep the soil moist: After t...
Local average minimum temperature increases of 10 degrees Celsius were found to be associated with 4.2 percent, 2.2 percent and 3.6 percent increases in antibiotic resistant strains of E. coli, K. pneumoniae, and S. aureus, respectively.
