Clouds

A cloud is a visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes up to several miles above sea level. They are generally produced by the condensation of water vapor. Other clouds, less commonly seen, are composed of smokes or dusts.

What is the difference between steam and water vapor?

The Steam and Vapor are the same thing i.e. Water in its gaseous state.

However Steam is formed by Forced Boiling and is at a pressure greater then the atmospheric pressure as used in a Steam Engine.

Water Vapour is free conversion of Water from Liquid to Gaseous Stage thru evaporation. It is in approximate equilibrium with atmospheric pressure

Steam is formed by by raising the Temperature (giving heat energy) of water above its Boiling Point i.e. 100 deg Celsius whereas evaporation of water (from water bodies) may occur at temperature way below the boiling point i.e. 30 deg Celsius. Drying of washed clothes is an example

Advantage of high pressure boiler over high pressure boiler?

High-pressure boilers can generate more steam at a higher temperature, which increases energy efficiency and reduces fuel consumption. They are also more compact in size and require less space compared to low-pressure boilers. Additionally, high-pressure boilers can achieve faster steam production and respond quickly to changes in demand.

The importance of clouds in the water cycle?

pooclouds or adds to existing clouds :) <---- this is some what true. But the reason is because when the water evaporates into the sky the water particles form or as in the water goes up and like basically forms the cloud. and there are 10 types of clouds in total! but 3 main types, they are cirrus, stratus, and cumulus.

Can you lay on a cloud?

no, a cloud is made of water and dirt particles. so if you were to lay on one you would fall through. this factor enables us to move through things such as fog.

What is it called when a glass cools down causing the air to vapor?

Condensation occurs when warm, moist air comes into contact with a cooler surface, causing the air to lose its heat and release water vapor which then condenses into droplets on the surface of the glass.

What does oktas mean?

Oktas are units of measurement used to estimate the amount of sky covered by clouds. Each okta represents one eighth of the sky covered by cloud. A sky with 0 oktas of clouds is clear, while a sky with 8 oktas is completely overcast.

What is a sudden energy discharge between parts of a cloud is called?

A sudden energy discharge between parts of a cloud is called lightning. Lightning is a natural electrical discharge produced in thunderstorms, typically accompanied by thunder, and can take on different forms such as cloud-to-ground or intracloud lightning.

Who invented water?

No body invented water!!

It has been with us (Earth) from time immemorial.

However, different civilisations, from history, wil have given it different names.

E.g. The Classical Greek - Hydros

The Romans - Aqua.

What is an eruption cloud?

An eruption cloud is a large plume of volcanic ash, gases, and other material that is ejected into the atmosphere during a volcanic eruption. These clouds can reach high into the atmosphere and pose hazards to aviation, health, and the environment.

Name a man-made gas which was phased out during the 1990s?

Chlorofluorocarbons (CFCs) were a man-made gas that was phased out during the 1990s due to their harmful effects on the ozone layer. They were commonly used in refrigerants, aerosol propellants, and foam-blowing agents.

What is the difference between a fog and a cloud?

Fog is a type of low-lying cloud that forms when the air near the ground becomes saturated with water vapor, whereas clouds can form at various altitudes in the atmosphere. Fog can reduce visibility near the surface, while clouds typically float higher in the sky. Fog is essentially a type of cloud that forms close to the ground.

What is another name for line of longitude?

A line of longitude is also called a meridian.

Meridians are half-great-circles that join the Earth's North and South Poles.

So they represent one-half of a polar circumference of the planet.

The Prime Meridian runs through England (Greenwich) and is 0 degrees longitude.

How long does it take to heat up spaghetti sauce?

When it begins to simmer/boil/bubble, it's probably hot.

Take a spoon and put it in the sauce. Remove the spoon and insert

it in your mouth. Is it hot? If so, the sauce is hot. If not,

it's not.

Seriously, it should only take a few minutes, dependent

on how high you have the burner. Too hot will scorch the sauce.

What is a build up of an electric charge in one place?

A build-up of an electric charge in one place is known as static electricity. This occurs when positive and negative charges accumulate on an object due to friction or induction, creating an imbalance of electrons. When this charge is discharged, it can result in sparks or a shock.

Does heat from a candle change air pressure inside a bag?

Yes, heat from a candle can increase the air pressure inside a sealed bag. As the air inside the bag heats up, it expands and creates higher pressure. This effect is commonly demonstrated in simple science experiments.

What type of particle leaves a long thin trail in a cloud chamber?

An ionizing particle, such as an alpha or beta particle, leaves a long thin trail in a cloud chamber due to its interactions with the gas atoms in the chamber, causing condensation along its path. This trail can help scientists track and study the particle's properties and behavior.

What is the Homosphere?

The homosphere is the portion of the earth's atmosphere, up to an altitude of about 50 miles above sea level, in which there is continuous turbulent mixing, and hence the composition of the atmosphere is relatively constant; as opposed to the heterosphere or exosphere, the higher regions in which the composition becomes stratified

In which of these places does peristalsis not occur?

Peristalsis does not occur in the central nervous system. It is responsible for the wave-like muscle contractions that move food through the digestive system, but it is not involved in neural signaling in the brain or spinal cord.

How does hot air move?

Heat can travel in air by convection, but radiation (electromechanical wave motion) is the most efficient way to transfer heat (energy) through air.

How do you change a boiler from low pressure to high pressure?

YOU DON'T the ASME /NBBI codes have certain requirements regarding boiler manufacturing and a high pressure boiler can cause severe damage if it is not properly designed and routine maintenance performed ....

If the dashboard temperature gauge in a 1991 Honda Accord stopped moving and the air that comes into the cabin is only slightly warm what could be the problem?

The issue could be a malfunctioning thermostat, which is responsible for regulating the engine temperature and allowing hot coolant to flow into the heater core. If the thermostat is stuck open, it can cause the engine to run colder than normal, resulting in only slightly warm air entering the cabin. Another possibility is a clogged heater core, which can restrict the flow of hot coolant and reduce the amount of heat transferred to the air.

How much does air pressure in psi change with temperature changes in degrees F?

Air pressure decreases by about 1 psi for every 10°F increase in temperature. Conversely, air pressure increases by about 1 psi for every 10°F decrease in temperature.

What will happen if Na2S mixed with water?

When Na2S is mixed with water, it will dissociate into sodium ions (Na+) and sulfide ions (S2-). This reaction will result in the formation of a basic solution due to the presence of the sulfide ions, which will hydrolyze in water to produce hydroxide ions.

What is the microwave utensils material made up of?

Microwave utensils are typically made from materials that are microwave-safe, such as glass, ceramic, and certain types of plastic. These materials are able to withstand the heat generated by the microwave without melting or releasing harmful chemicals into your food. It's important to check the manufacturer's guidelines to ensure that your utensils are safe to use in the microwave.

Why is 92 Pontiac Sunbird taking on water inside?

Water inside a car could be due to a leaking window seal, sunroof, or door seal allowing rainwater to enter. It could also be caused by a clogged drain in the sunroof or air conditioning system. Inspecting these areas for leaks and blockages should help identify the source of the water.
