Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The terminal velocity of a large blood droplet is greater than the terminal velocity of a small blood droplet. This is because larger droplets have more mass, which increases their gravitational force and air resistance, allowing them to fall faster until they reach a balanced terminal velocity.
How does the impact of a water droplet splash vary depending on the surface it lands on?
The impact of a water droplet splash varies depending on the surface it lands on due to factors such as surface tension, texture, and angle. On a smooth surface, the droplet may spread out evenly, while on a rough surface, it may break into smaller droplets or splash in different directions. The angle of the surface can also affect the height and direction of the splash.
what happens when gravity works on large drops of water?
When gravity acts on large drops of water, the drops become unstable and tend to break apart into smaller drops. This is because the force of gravity exceeds the surface tension that holds the water droplet together, resulting in the droplet stretching and eventually separating into smaller droplets.
What are the two theories of raindrop formation?
The two theories of raindrop formation are the collision-coalescence theory and the ice crystal (Bergeron) process. The collision-coalescence theory suggests that raindrops form when smaller cloud droplets collide and merge together. The ice crystal process involves supercooled water droplets colliding with ice crystals, leading to the growth of raindrops.
How do water droplets falling out of a thundercloud get bigger as they fall towards the earth's surface?
they get bigger because the water droplets are cold and there is also water vapour in the air which is hotand when they meet the water vapour changes back to water droplets which then combine with the water droplets falling from the thunder cloud!!
What is the formation of a large droplet of precipitation by the combination of smaller droplets called?
The formation of a large droplet of precipitation by the combination of smaller droplets is called coalescence. This process occurs when smaller droplets collide and merge together to form a larger droplet, ultimately leading to precipitation.
Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The terminal velocity of a large blood droplet is greater than the terminal velocity of a small blood droplet. This is because larger droplets have more mass, which increases their gravitational force and air resistance, allowing them to fall faster until they reach a balanced terminal velocity.
Why does cloud droplet and ice crystal size influence the probability that clouds will produce precipitation?
Cloud droplet and ice crystal size influence the probability of precipitation because larger droplets or crystals have a higher terminal velocity and are more likely to fall as precipitation. Smaller droplets or crystals may evaporate before reaching the ground, reducing the likelihood of precipitation. Additionally, larger droplets or crystals can collide and coalesce more easily, leading to the formation of larger raindrops or snowflakes that are more likely to fall as precipitation.
What has the author Afsoon Amirzahed Goghari written?

What is the primary difference between a cloud droplet and a raindrop?
The primary difference between a cloud droplet and a raindrop is their size. Cloud droplets are much smaller, typically less than 0.02 mm in diameter, while raindrops are larger and can range from 0.5 to 6 mm in diameter. Cloud droplets need to grow through collision and coalescence to form raindrops and eventually fall to the ground as rain.
What is collision coalescence theory of cloud precipitation?
One theory explaining how the behavior of individual droplets leads to the formation of clouds is the collision-coalescence process. Droplets suspended in the air will interact with each other, either by colliding and bouncing off each other or by combining to form a larger droplet. Eventually, the droplets become large enough that they fall to the earth as precipitation. The collision-coalescence process does not make up a significant part of cloud formation as water droplets have a relatively high surface tension. Sources: Wikipedia
What is the proccess called when cloud droplets collide to form larger droplets?
Coalescenceno its dew point or dewpoint.
What is a water droplet in a cloud that becomes rain when its diameter increases to how many times its original size?
A water droplet in a cloud becomes rain when its diameter increases to around 50 times its original size. This process is known as coalescence, where smaller droplets merge together to form larger droplets, eventually becoming heavy enough to fall as rain.
What process cause the water droplet to fall to earth as precipitation?
Water droplets fall to Earth as precipitation when they become too heavy to remain suspended in the atmosphere. This can occur due to processes like coalescence, where smaller droplets combine to form larger ones, or when the droplets freeze into ice particles. Once these droplets or ice particles reach a critical size, gravity pulls them down as precipitation.
How does the impact of a water droplet splash vary depending on the surface it lands on?
The impact of a water droplet splash varies depending on the surface it lands on due to factors such as surface tension, texture, and angle. On a smooth surface, the droplet may spread out evenly, while on a rough surface, it may break into smaller droplets or splash in different directions. The angle of the surface can also affect the height and direction of the splash.
How far can a droplet travel after a cough or sneeze?
A droplet expelled during a cough or sneeze can travel several feet, typically up to 6 feet or more, depending on factors like the force of the cough or sneeze and environmental conditions. Larger droplets generally fall to the ground quickly, while smaller droplets can remain suspended in the air for longer distances and times. This is why maintaining physical distance is important in preventing the spread of respiratory infections.
Does evapoartion depend upon droplet size for water?
yes, in some manner... rate of evaporation depends upon the surface area the liquid is covering. the more the surface area. the more the rate of evaporation. in this case, the more area the drop would cover on the body or on any surface, the more quickly the drop would evaporate!
