Explain in terms of particles why energy must be given to a liquid if it is to be changed to a gas?
To change a liquid into a gas, the particles in the liquid must overcome the attractive forces holding them together to become a gas where the particles are more spread out and have higher energy. This requires energy input to break these intermolecular forces and increase the kinetic energy of the particles to transition from the liquid phase to the gaseous phase.
What world cities have the fewest days of sunshine?
Some cities with the fewest days of sunshine include Ushuaia in Argentina, Reykjavik in Iceland, and Seattle in the United States. These cities are typically located at higher latitudes or experience a lot of cloud cover due to their geographical location.
What is the air pressure in Peru highland?
It's the preassure, I mean, since the highlands are HIGH, the distance between the .. sky let's say .. and the lands is less than the one from the coast, so the air preassure is much stronger. If you are not accustomed to it, you will have some difficulty breathing, and if you run or whatever that requires a modarated physical movement you will feel like no air is coming into your lungs, but anyways, I think that 3 days are enough to get used to the air preassure :D
The number of comets in the Oort cloud is probably about?
It is estimated that there are billions or even trillions of comets in the Oort Cloud. These comets are believed to be remnants from the early solar system and are located in a distant region surrounding our solar system.
Can relative humidity be zero?
No, relative humidity cannot be zero as it represents the amount of water vapor present in the air relative to the maximum amount it could hold at a given temperature. If the relative humidity were zero, it would mean that the air is completely dry and unable to hold any moisture, which is not possible in natural atmospheric conditions.
What kind of cloud does a thunderstrom form in?
Thunderstorms typically form in cumulonimbus clouds, which are large, towering clouds associated with thunder, lightning, heavy rain, and sometimes hail. These clouds have strong vertical development, reaching high into the atmosphere, and are often associated with severe weather events.
A hygrometer measures the humidity level in the air and other gases What humidity?
Humidity refers to the amount of water vapor present in the air. A hygrometer measures this humidity level, expressing it as a percentage relative to the maximum amount of water vapor the air can hold at a given temperature. This helps in understanding the moisture conditions in the environment.
What snow and rain have in common?
Snow and rain are both forms of precipitation that occur in the atmosphere when water droplets or ice crystals coalesce and fall to the ground. They are essential components of the Earth's water cycle, playing a crucial role in replenishing freshwater sources and sustaining ecosystems. Both snow and rain are influenced by factors such as temperature, humidity, and atmospheric conditions.
Is converting frost to water vapor exothermic?
Converting frost to water vapor is an endothermic process because it requires energy input to break the intermolecular forces holding the solid ice together. The energy is used to overcome the forces of attraction between water molecules in the solid phase so they can escape into the gas phase.
What is a physical process by which vapor becomes liquid or solid the opposite of evaporation?
Condensation is the process by which vapor turns into liquid or solid, the opposite of evaporation. This occurs when the temperature of the vapor decreases, causing the molecules to slow down and come closer together, forming a liquid or solid state.
What type of precipitation does cumulus cloud produce?
normally cumulus clouds do not produce precipitation. It is cumulonimbus clouds that form rain or snow depending on the season.
What color are nimbostratus clouds?
Cumulonimbus cloud's colour depends on the conditions, time and your location. In broad daylight, with the sun shining on them they are usually white, like all clouds in daylight. The base of the cloud is dark grey because of the thick cloud blocking the sun. Depending on the cloud thickness, the underside of a cumulonimbus can even be black.
When there is a lot of hail and ice crystals in the cloud, it can take on a green or turquoise appearance.
In the sunset, the cloud can appear brown, orange or red. At dusk, the cloud can appear light blue, and at night, it is usually hard to see untill lightning illuminates it.
As a substance changes from a liquid to a gas the space between its particles?
......... distances become 100 to 1000 times bigger
How does mountain lifting cause air to rise?
As A rule the air is moveing in one direction, even though it will change direction momentarilly, All this air is going to travel in A fairly uniform direction, When it hits A mountain The air that is lower to the valley will continue to travel along its path and the mountain will cause it to rise up the side of the mountain, This air will compress the air that is already traveling in the upper levels, pushing the upper air MORE upward, as the air gets toward the top of the mountain, there is so much air trying to pass the mountain that the air will increasingly go upward in A more vertical direction. Is that confusing? I hope someone can make it easier to understand,. The jist is, More air, less room.
What point does water in the air condense when air is cooled?
Water vapor in the air condenses into liquid water when the air is cooled below its dew point temperature, which is the temperature at which the air becomes saturated and can no longer hold all the moisture it contains as vapor. This causes the water vapor to turn into liquid droplets, forming clouds, fog, or dew.
Is it true condensation occurs when water vapor is heated?
No, condensation occurs when water vapor is cooled and changes from a gas to a liquid. Heating water vapor would cause it to remain in its gaseous state or potentially transform into steam, which is still a gas.
What is the change of state from liquid to gas is called?
The change of state from liquid to gas is called vaporization.
Why is particulate matter important for clouds to form?
Particulate matter in the atmosphere, such as dust or pollution, serve as nuclei for water vapor to condense and form cloud droplets. Without these particles, it would be difficult for water vapor to condense and form clouds, as they provide a surface for water molecules to adhere to and grow into droplets.
What happens when the wet and dry bulb thermometers are close together?
When the wet and dry bulb thermometers are close together, it indicates that the air is close to being saturated with moisture. This can help determine the relative humidity of the air. If the readings are the same, it means the air is fully saturated and the relative humidity is 100%.
What will happen to the barometric pressure on the approach of a cold front?
As a cold front approaches, the barometric pressure will typically decrease. This drop in pressure is due to the denser, cold air displacing the lighter, warm air. This change in pressure can be a signal of impending weather changes such as storms or precipitation.
Particles escape from the surface of a nonboiling liquid and enter the gas state?
States of matter are determined by the amount of Kinetic Energy they have. When a gas becomes a liquid, it loses energy, and the particles slow down enough to affect each other. This is why liquids have a volume.
Which Water vapor in the air condenses into liquid droplets when the water reaches blank?
saturation point
Which state of water is most ordered a. solid b. liquid c. gas?
The most ordered state of water is solid (ice). In the solid state, water molecules are closely packed in a regular pattern with strong intermolecular forces holding them in place. In contrast, in the liquid and gas states, water molecules have more freedom of movement and are less ordered.
The value of atmospheric pressure at Johannesburg?
The average atmospheric pressure in Johannesburg is around 860 hPa (hectopascals). This can vary depending on weather conditions and altitude.
