Properties of water from a glacier and geyser

Answers

Answer 1
Answer: Water has three phases: liquid, gas, and solids. Can be easily changed to phase in the temperature range that is in the earth's surface. Global water cycle is based on three phases of water.

Water in the solid phase (ice) is lighter than the liquid phase. This is an anomaly; in general, other compounds in the solid phase has a density greater than the liquid phase so that it will sink. The implication: If the ice is heavier than water, so we just have sedikiit sea! Thewater in the polar regions of seasonal frozen, but the ice sheets willmelt during the summer, or to shift to a more warm and melted there. If ice were heavier than water, it will sink to the bottom of the ocean and isolated from the hot sun. Thus,most of the ocean would be composed of a layer of ice underneath, just afew meters from the surface which is a layer of water during thesummer. Furthermore, it would be very limiting evaporation and cloud formation, which is a source of fresh water on land.

Water can dissolve the salt and gas but can be easily separated as a pure vapor. The sun's rays evaporate water from the ocean, but the salts remain in the sea. The result: water vapor (clouds) driven wind toward land, thencondenses into rain, which is a source of fresh water on land, then backagain to the sea.

Water easily dissolves CO2 and become effective acid solution. In addition to the atmosphere, the CO2 source is also present in the root zone of the soil. All rock will undergo interaction with acid water is and will be eroded and transported to the sea.

Water that has a low viscosity and not sticky. As a result: (1) to flow as surface water water efficiently. (2) Can penetrate (infiltration) into the ground. (3) Flow through permeable rocks.

Water weighs enough to be moved by the force of gravity. As a result: allowing the flow of groundwater and surface water runoff.

Water has a density that is appropriate. The result: no water vapor out of the Earth.

Water and water vapor through. As a result: sunlight can enter thr
ough the air and through tens of meters of depth of the sea and lakes, as energy requirements of life.

Water including greenhouse gases. As a result: maintaining water balance in the Earth's temperature.

Some land plants have evolved specialized vascular tissues that have allowed them to thrive on land. The developement of these structures was necessary becauseLand plants need to extract water from the ground and move it to the other structures of the plant.

Land plants don’t really need these structures as they can absorb water from the air through their leaves.

What would be an example of a chemical change that took a long time to occur?

Answers

The rusting of iron is an instance of a chemical change that takes a long time to occur.

What is rusting?

Rust is an iron oxide, which is a typically reddish-brown oxide formed by the catalytic reaction of iron and oxygen in the presence of water or air moisture.

Rust is made up of hydrous iron(III) oxides and iron(III) oxide-hydroxide and is commonly associated with refined ironcorrosion.

Rusting is defined as the chemical process by which a red or orange coat forms on the surface of metals. Corrosion includes rusting.

When iron or its alloys are exposed to moist air, rust forms. The hydrated oxide is formed when oxygen and water in the air react with the metal.

(Fe2O3) is the well-known red form of rust, but iron has other oxidation states and can form other colors of rust.

Thus, this is the example of a chemical change that took a long time to occur.

Which type of gloves protects your hands from hazardous chemicals? A. Latex gloves B. Padded cloth gloves C. Vinyl or neoprene gloves

Answers

C. Vinyl or neoprene gloves provide protection against hazardous chemicals due to their resistance to chemical exposure. Latex gloves can be permeable, and padded cloth gloves are not designed for chemical protection.

C. Vinyl or neoprene gloves are the appropriate choice for protecting hands from hazardous chemicals. Here's why:

1. Chemical Resistance: Vinyl and neoprene gloves offer excellent resistance to a wide range of chemicals, including acids, bases, solvents, and oils. This resistance creates a barrier that prevents hazardous chemicals from coming into contact with your skin.

2. Latex Allergies: Latex gloves (option A) can cause allergic reactions in some individuals, which can be severe. It's important to avoid latex gloves when working with hazardous chemicals to prevent potential allergic responses.

3. Physical Protection: Padded cloth gloves (option B) are typically designed for physical protection and comfort, not for chemical resistance. They may not provide an effective barrier against chemical exposure, making them unsuitable for this purpose.

4. Versatility: Vinyl and neoprene gloves are versatile and can be used in various laboratory, industrial, and healthcare settings where protection against chemical hazards is necessary.

5. Durability: These gloves are known for their durability and resistance to wear and tear, ensuring that they maintain their protective properties even during prolonged use.

It's essential to choose the right type of gloves based on the specific chemicals you are handling and their compatibility with the glove material. Always consult safety guidelines and material compatibility charts to select the most appropriate gloves for your specific chemical-handling tasks, ensuring the safety of your hands and skin.

the correct answer would be A. Latex Gloves. vinyl or neoprene gloves will be eaten by most highly toxic chemicals and some lower toxicity chemicals and padded cloth gloves will just soak up the chemical.

The concentration of a solution can be expressed in(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

Answers

Answer:

(2) parts per million

Explanation:

Concentration of a solution can be expressed in terms of parts-per-million (ppm).

ppm is usually used in the context of measuring very small concentrations particularly the amount of contaminants. It represents 1 part of the contaminant in 100000 parts of the total.

It is expressed as:

1 ppm = 1 mg / L

1 ppm = 1 mg/ Kg

(I ) milliliters per minute
(2) parts per million
(3) grams per Kelvin
(4) joules per gram

30. The of an object is different on every
planet in the solar system.

Answers

Answer:

Weight

Explanation:

  • The weight of an object is different on every planet in the solar system.
  • Weight is the gravitational pull of an object towards the surface of a planet.
  • It is measured in Newtons, using a spring balance .
  • Weight changes from one place to another depending on the gravitational acceleration of a surface.
  • For example, the weight of an object on the surface of the earth is different from the weight of the same object on the surface of the moon.
  • Mass of an object, on the other hand, remains constant and is the same on every planet in the solar system.

Answer:
