Jugular venous pressure is typically measured in millimeters of water (mm H2O) because it provides a more sensitive and precise way to assess changes in venous pressure. Using mm H2O allows for a greater resolution in detecting small changes in pressure compared to using other units such as centimeters of water or millimeters of Mercury.
What else can I help you with?
What volume in liters of O2(g) is required to form 50 L of H2O(g) Assume that both gases are measured under the same conditions.?
To form water (H2O) from hydrogen (H2) and oxygen (O2), the balanced chemical equation is 2 H2(g) + O2(g) → 2 H2O(g). From the equation, 2 volumes of H2 produce 2 volumes of H2O, meaning 1 volume of O2 produces 2 volumes of H2O. Therefore, to form 50 L of H2O, you would need 25 L of O2(g).
What temperature turns water into solid?
Water is a solid at all temperatures from 0 degrees C downwards. That is at normal atmospheric pressure.
How many grams are there in 1.57 moles of water?
1 mole H2O = 18.015g H2O 1.57mol H2O x 18.015g H2O/1mol H2O = 28.3g H2O
Is chemical formula H2O physical or chemical property?
The chemical formula H2O itself is a chemical property because it represents the specific composition of water molecules. Physical properties, on the other hand, describe characteristics that can be observed or measured without changing the substance's chemical identity.
At room temperature all samples of liquid H2O must have the same what?
At room temperature, all samples of liquid H2O must have the same boiling point, which is 100 degrees Celsius or 212 degrees Fahrenheit at standard atmospheric pressure.
What is the abbreviation for h2o pressure?
psi.
Unit of static pressure of fan?
Usually, due to the relatively low value of the static pressure of a fan, the unit that this pressure is expressed is milibar, mm H2O, psi, mm Hg, kPa, hPa. In the US, inches H2O.
What does the subscript l on H2O l signify?
The "l" subscript on H2O signifies that water is in its liquid state at room temperature and pressure.
What is the bp of H2O?
The boiling point of water is 100 degrees C
One of the following processes is spontaneous at 298 K Which one A. H2O l H2O g 1atm B. H2O l H2O g 0.10atm C.H2O l H2O g 0.010atm?
Process C (H2O l -> H2O g, 0.010 atm) is the most spontaneous at 298 K because it has the lowest pressure of water vapor, favoring the vaporization of liquid water. As pressure decreases, the entropy change due to the increase in disorder upon vaporization becomes more significant, driving the process towards spontaneity.
If the column of water in the water barometer rose to a height of 39 feet what would the atmospheric pressure be in mm Hg?
Given: 39ft. H2O Conversions you can look up or know: 1ft=12in 1in=25.4mm 1mmHg=13.6mm H2O 39ft H2O (12in H2O/1ft H2O)(25.4mm H2O/1in H2O)(1mm Hg/13.6mm Hg)= 874.0588235 in calculator, but 874 with sig figs.
Does baking soda raise your PH in your body?
Baking soda does raise your blood pressure. Since Baking soda raises blood pressure and if your blood pressure is high then there will be a higher diffusion of Nutrients, O2, Proteins at the arterial end of the capillary into the Interstitial Fluid due to a higher pressure gradient and thus at the venous end of the capillary a low concentration of CO2 (produced by the cells) will diffuse from the interstitial fluid into the venous end of the capillary. So overall the dissolved CO2 in the blood will be low. So how does CO2 relate to pH? we know that CO2 combines with H2O to form Carbonic Acid; Carbonic Acid in turn disassociates to form H+ and HCO3- CO2 + H20 --> H2CO3 --> H+ + HCO3- Since the CO2 level in the blood is low there will be Less H+ in the blood and therefore the pH of the blood will be high, Causing Alkalosis.
What molecule has the highest vapor pressure Br2 H2O NCl3?
Among the given molecules, bromine (Br2) has the highest vapor pressure due to its relatively low boiling point and weak intermolecular forces between its molecules. Water (H2O) has a lower vapor pressure compared to bromine because of its stronger hydrogen bonding. Nitrogen trichloride (NCl3) has the lowest vapor pressure since it is a polar molecule with stronger intermolecular forces compared to the other two molecules.
What is the difference between beaker and graduated cylinder in terms of measuring a volume of liquid?
beaker holds the H2o been measured by the graduated cylinder
What form water will be at four degree centigrade?
At standard atmospheric pressure, Water (H2O) will be in the liquid state.
40CM OF H2O how many hg of mercury?
Everything else (temperature, atmospheric pressure, environment) being the same, the only factor you need to consider is the (relative) densities of H2O and Hg. The density of water = 1 g.cm-3 at T=20oC and 1 standard atm. The density of Hg = 13.5 g.cm-3. Hence, the pressure for a column of H2O 40 cm high in vacuum is the same as that for a column made of 40 [cm] / 13.5 = 2.96 cm of liquid Hg in vacuum. * Note that the atmospheric pressure is indicated by the height of the liquid in an inverted tube (open-end facing down) with a (partial) vacuum at the top of the tube. =====================
What is low vapor pressure?
Vapor pressure refers to the force exerted by gaseous molecules of a liquid. Usually this is measured in a closed system. For example, in a water bottle some H2O molecules are able to move from liquid to gas phase at room temperature. The molecules that do this create vapor pressure. Low vapor pressure is usually observed in substances that have a low boiling point or if it is being held at a low temperature.
