Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L

A nurse who is preparing to boost a client up in bed instructs the client to use the overbed trapeze. which risk factor for pres
atroni [7]
I will try my best to answer your question

Shearing forces-rationale: friction, impaired circulation, localized pressure, and shearing forces are all risk factors of pressure ulcer development; trapeze use reduces shearing forces. shearing forces (opposing forces that cause layers of skin to move over each other, stretching and tearing capillaries and, eventually, resulting in necrosis) can occur as clients slide down in bed or are pulled up in bed. subcutaneous skin layers adhere to the sheets while deeper layers, muscle, and bone slide in the direction of movement. to reduce shearing forces, the nurse should instruct the client to use an overbed trapeze, place a draw sheet under the client to move him up in bed, and keep the head of the bed no higher than 30 degrees.client needs category: physiological integrityclient needs subcategory: basic care and comfortcognitive level: applicationreference: taylor, c., et al. fundamentals of nursing: the art and science of nursing care, 6th ed. philadelphia: lippincott williams & wilkins, 2008, p. 1196.

If a rock disintegrates by chemical weathering into small grains of similar composition, would this be considered reproduction?
Serhud [2]
No, because it is still the same rock, and the rock would eventually erode into nothing.
