This type of heat transfer is trapped in green houses. Conduction, Convection, Or Radiation and why is it conduction, convection, or radiation?

Answers

Answer 1

Answer: This transfer is radiation. This type of heat transfer is composed of electromagnetic waves from the Sun either through infrared or ultraviolet rays. Radioactive heat transfer is the only way to transfer heat from one place to another without a medium.

Answer 2

Answer:

Answer:

infrared radiation

Explanation:

Light from the Sun passes through the glass roof to heat plants and the ground inside the greenhouse. These objects then emit infrared radiation, which is absorbed in the glass roof. Thermal energy is trapped in the greenhouse, keeping the building warm.

According to the kinetic molecular theory, whichstatement describes the particles in a sample of an
ideal gas?
A. The particles are constantly moving in circular
paths.
B. The particles collide, decreasing the total energy
of the system.
C. The particles have attractive forces between them
D. The particles are considered to have negligible
volume.

Answers

Answer:

D. The particles are considered to have negligible volume.

Explanation:

According to the Kinetic Molecular Theory for ideal gases

- Gases are composed of larges molecules which are in constant random motion in a straight line

- The volume of the gas particles is negligible compared to the total volume in which the gas is contained.

- The attractive and repulsive forces between gas molecules is insignificant ie There are no interactive forces.

- The collisions of the particles are perfectly elastic and energy is being transferred between the particles but the total energy remaining constant

You can measure length with the greatest precision using a tape measure marked in _____.A. meters
B. kilometers
C. millimeters
D. centimeters

Answers

Answer:

The answer is C

Explanation:

Precision generally means been accurate (and can be loosely interpreted to mean been exact). Length is averagely measured in meters. However, in order to get the actual length of a substance using a tape, millimeters give the most accurate length (of all the options) as it provides the length to the smallest details (of all the options provided). The illustration below shows the relationship between millimeters and the rest of the options.

while 1 kilometer = 1000 meters

1 meter = 100 centimeters

1 centimeter = 10 millimeters

From the relationship above, millimeters is clearly the most precise of all the options provided.

You can measure length wiht the greatest preciaion using a tape measure marked in milimeters.

Answer: C. milimeters.

How many pairs of non-bonding electrons are in a silicon disulfide molecule?

Answers

Silicon disulfide (SiS2) is a covalent compound consisting of silicon (Si) and sulfur (S) atoms. To determine the number of pairs of non-bonding electrons in a silicon disulfide molecule, we can first calculate the total number of valence electrons in the molecule.

Silicon (Si) has 4 valence electrons, and sulfur (S) has 6 valence electrons each. Since there are two sulfur atoms in SiS2, that's a total of 2 x 6 = 12 valence electrons from sulfur.

Now, add the valence electrons from silicon and sulfur:

4 (Si) + 12 (S) = 16 valence electrons in total.

In a covalent compound like silicon disulfide, all the valence electrons are involved in bonding, either in forming bonds (shared electrons) or as non-bonding pairs.

Since SiS2 forms two covalent bonds (Si-S-Si), each involving two electrons, there are 4 electrons used for bonding (2 pairs of bonding electrons). Therefore, the remaining 16 - 4 = 12 electrons are non-bonding pairs.

So, there are 12 pairs of non-bonding electrons in a silicon disulfide (SiS2) molecule.

If a sample of iron with a density of 7.80 g/cm3 displaces 75.0 mL of water when placed in a beaker, what is its mass?

Answers

1 mL = 1 cm³

75.0 mL = 75.0 cm³

Density = mass / volume

7.80 = mass / 75.0

mass = 7.80 x 75.0

mass = 585 g

hope this helps!

If a sample of iron with a density of 7.80 g/cm^3 displaces 75.0 mL of water when placed in a beaker, its mass is 585 g.

Starch and cellulose are both produced by plants, yet one is easily digested by animals and the other is not. Discuss the differences in the structures of these two molecules and how this may impact whether they can be digested.

Answers

Starch andcellulose have the same substance but different structures. They are bothpolysaccharides. The basic unit of a polysaccharide is the glucose. Glucose,which contains carbon, hydrogen, and oxygen, have two forms. The alpha-glucosewith an alcohol group attached to carbon 1 is down and the beta-glucose withthe alcohol group attached to carbon 1 is up. Starch is the alpha-glucose whilecellulose is the beta-glucose. Starches are linked into a straight chain whereasthe cellulose are connected like a pile of stack paper. When the human bodyeats starch, it can digest the starch but not the cellulose because it has noenzyme that can break it down.

Final answer:

Starch is easily digested by humans due to the presence of enzymes breaking its α-glucose bonds, while humans lack the enzymes to break the β-glucose bonds in cellulose, rendering it indigestible but essential as dietary fiber.

Explanation:

Starch and cellulose are both polysaccharides produced by plants. Their structural differences, however, determine how they can be digested by animals. Starch is made up of α-glucose molecules, which are joined together by 1-4 and 1-6 glycosidic bonds, forming a helical structure. The human digestive system has enzymes like amylase that can break these bonds, enabling the digestion of starch.

1)Ag (silver) tarnishes..physical or chemical property2)An apple is cut..physical or chemical property

Answers

Tarnishing of silver is a chemical property while an apple being cut is a physical property.

What are physical properties?

Any property which describes the state of a physical system is called as a physical property.Changes in physical properties are used to describe changes between the states. They are often related to as observable properties.

Physical property which can be quantified is a physical quantity. These are also classified further with respect to their directionality. Isotropic properties do not change with direction of observation while anisotropic properties change with direction of observation.

Physical properties are differentiated from chemical properties by the way they determine how a substance behaves in a chemical reaction.

Ag tarnishing is a chemical change.(because the chemical composition of the silver is changing into a different one.). Apple being cut is a physical change because the chemical composition of the apple remains the same, but the apple itself changes to a smaller physical state.
