The diagrams below represent three phases of matter labeled A,B and C. Which table correctly identifies the phases of matter represented by the diagrams? *

Answers

Answer 1

Answer:

The correct answer is 1

Explanation:

From the above, we will note the following:

Diagram A is liquid because it takes the shape of its container and it also has a specific volume. The particles are not tightly packed.

Diagram B is gas because the particles are freely moving colliding with one another and with walls of the container.

Diagram C is solid because the particles are tightly packed and are not freely moving.

Therefore, Option 1 is the correct answer.

Which statement best supports the idea that water conservation is important for human societies?

OA Once humans use water, it cannot be reused ever again,

OB. Only about 1% of the freshwater on Earth is easily accessible.

OC Water is constantly being lost from the hydrosphere

OD. Most land animals use salt water instead of freshwater.

Answers

Answer:

Only about 1% of the freshwater on Earth is easily accessible.

Explanation:

Freshwater accounts for a minimal proportion of water resources on planet earth. About 70 percent of the world surface area is covered by water, but only about 2.5 percent of this mass of water is fresh. The remaining are marine or salt water. Amazingly, just about 1 percent of this freshwater is easily accessible. The other 1.5% is trapped in glaciers and snowfields.

This underscore the need for water conservation on the planet since fresh water is a scarce resource and people living in many areas have no access to fresh water.

Using the formula M=dx v, Calculate the mass of a liquid with a density of
17.5 g/mL and a volume of 7mL.

Answers

Answer:

The answer is 122.5 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume = 7 mL

density = 17.5 g/mL

We have

mass = 17.5 × 7

We have the final answer as

122.5 g

Define the concept of Energy in your own words

Answers

Answer:

In general, the word energy refers to a concept that can be paraphrased as "the potential for causing changes", and therefore one can say that energy is the cause of any change. The most common definition of energy is the work that a certain force (gravitational, electromagnetic, etc) can do. Due to a variety of forces, energy has many different forms (gravitational, electric, heat, etc.) that can be grouped into two major categories: kinetic energy and potential energy. According to this definition, energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example. Energy has no direction in space, and is therefore considered a scalar quantity. Energy is a conserved quantity, meaning that it cannot be created or destroyed, but only converted from one form into another. Thus, the total energy of the universe always remains constant. One form of energy can be readily transformed into another; for instance, a battery converts chemical energy into electrical energy.

Answer:

A force is the strength or energy as an attribute of physical action or movement.

Explanation:

In smaller words, a force is a form of energy caused from a push or a pull on an object. A force happens when two objects interact with each other. For example, when you throw a ball you are using force.

Describe Thomson’s and Millikan’s contributions to atomic theory.

Answers

Answer:

Thomson passed an electric current through sealed glass tubes filled with gases. Thomson concluded that electrons must be parts of the atoms of all elements. Millikan determined the charge and mass of the electron.

Explanation:

Thompson discovered electrons and proposed the plum - pudding model of the atom. Millikan measured the charge to mass ratio of an electron.

In the early days of the atomic theory, working with his cathode ray tube, J.J Thompson discovered electrons. His discovery of electrons led him to propose a model which depicted the atom as a sphere of positive charges into which negative charges were embedded. This is the plum-pudding model of the atom.

Using his famous oil-drop experiment, R.A Millikan successfully measured the charge to mass ratio of the electron and thereby determined the magnitude of charge on the electron.

Answer:

The discovery of optics gave scientists instruments such as microscopes and telescopes.

Explanation:

The period between the 16th-8th century was called the period of the scientific revolution. At this time, the foundations of our modern science was laid.

One of the characteristic of this period was the emphasis on the scientific method which upheld results from reproducible experiments.

Nicolaus Copernicus, Francis Bacon and Isaac Newton were leading names in this period.

It was within this period that the discovery of optics gave scientists instruments such as microscopes and telescopes and scientific examination of the celestial bodies was launched.

A model stands on a scale and finds her weight to be 105 pounds. If
the pressure exerted by her feet on the scale is 2.16 pounds per
square inch, what is the area of her feet in cubic centimeters?
__cm2

Answers

Answer:

313.5cm²

Explanation:

Given parameters:

Weight of model = 105pounds

Pressure applied on the scale by model = 2.16pounds per square inch

Unknown:

Area of her feet in cm² = ?

Solution:

Pressure is the force per unit area;

Pressure = [tex]\frac{Force}{Area}[/tex]

Input the parameters and solve;

2.16 = [tex]\frac{105}{Area}[/tex]

105 = 2.16 x Area

Area = [tex]\frac{105}{2.16}[/tex] = 48.6in²

We need now to convert the in² to cm²

1in² = 6.45cm²

48.6in² = 48.6 x 6.45 = 313.5cm²
