Answer : The vapor pressure of the dry oxygen gas is, 736.2 torr
Explanation : Given,
Volume of sample of oxygen = 500 mL
Vapor pressure of oxygen + water = 760 torr
Vapor pressure of water = 23.8 torr
Now we have to determine the vapor pressure of the dry oxygen gas.
Vapor pressure of the dry oxygen gas = Vapor pressure of (oxygen + water) - Vapor pressure of water
Vapor pressure of the dry oxygen gas = 760 torr - 23.8 torr
Vapor pressure of the dry oxygen gas = 736.2 torr
Thus, the vapor pressure of the dry oxygen gas is, 736.2 torr
A transverse wave is a wave is a wave in which the particles in the medium oscillate in a direction that is perpendicular or at 90 degrees to the direction in which the wave propagates. Light waves or electromagnetic waves are a good example of transverse waves. When an electromagnetic wave propagates, the medium in which it propagates vibrates in a direction perpendicular to the direction of travel.
A longitudinal wave is a wave in which the particles of the medium oscillate in a direction parallel to the direction in which the wave is travelling. Sound waves are good examples of longitudinal waves. When sound propagates, the particles of the medium which it travels through will vibrate in the direction in which the wave is travelling.
Similarities
- Both transverse and longitudinal waves carry energy.
- Both transverse and longitudinal waves obey the wave equation.
- Both transverse and longitudinal waves show behavior such as refraction, reflection, absorption, diffraction, etc.
Differences
The main difference is that for longitudinal waves, the particles in the medium will vibrate in the direction of the wave and that for transverse waves, the motion of the particles in the medium is in a direction perpendicular to the direction of propagation of the wave.
Answer:
The answer for number one is .A
The answer for number two is heat rises
Explanation:
The correct answer is B: dormancy. In response to unfavourable environmental conditions, such as over winter months, plants are able to enter a state of little to no growth, called dormancy. In addition to reducing or halting growth over dormancy periods, <span>deciduous</span> trees shed their leaves over winter, thereby avoiding water loss. Most trees also bud over spring and summer periods, when conditions are more favourable.
