What is Chemistry? Concept 1

Now, as you start to learn about chemistry, you may ask yourself what exactly is chemistry? Well, chemistry is the study of matter. It's nature, properties and the changes it undergoes. Now, when I say the term matter, that's just anything that occupies space because it has volume and mass. And when it comes to chemistry, it serves as a central science and foundation that links together other scientific disciplines. So when you click on the next video, you'll see how chemistry plays a central role in our understanding of other types of sciences.

What is Chemistry? Practice 1

So just the name for the science that studies the physics of rocks and the earth. Here are options are geology, biology, environmental science and nuclear chemistry. So here we're taking a look at rocks and the Earth's we're looking at sediments and stuff like that because we're dealing with rocks itself, that most likely means that we're dealing with our scientific discipline of geology, G. L. Standing for the earth itself. All right, So here, when we're talking about rocks more talking about uh sediment earth itself, all files under the scientific discipline of geology.

What is Chemistry? Example 1

So just a name for the science that studies the motor functions and responses of the venus flytrap here, if we take a look at our options, we have biochemistry, physics, plant sciences and health sciences. Well, we know that the venus flytrap is one of those pretty famous types of plants. We might have seen images, or you might have seen images of it basically devouring insects, spiders, even frogs. Depending on the size of the venus fly trap itself. Because it's a famous type of plant, it would make sense that would fall under plant sciences. That mean options see is are correct answer.

What is Chemistry? Concept 2

As I stayed in the last video, Chemistry serves as the central science that linked together other scientific disciplines. So if we take a look here, we have chemistry in the Senate From it, we can see that it's connected to all these other types of subjects. Each one of these subjects has an umbrella scientific discipline connected to it. So, for example, the first one, we have anatomy, physiology, and genetics. This is under the umbrella of biology. So there's a direct connection between chemistry and biology and biology and chemistry both ways. Biology is also connected to these other disciplines. We could think of the chemistry itself serving as the Sun and all of these scientific disciplines, the planets that orbited. They're connected to one another because they're part of the same solar system and they're all connected to the Sun because they orbit the sun. All right. So for the next one, so we're gonna go around this. So for the next one, we have molecular biology, immunology, endocrinology and genetic engineering. This is all under biochemistry. So biology and chemistry mixed together. Next we have here uh pharmacology, nutrition, clinical chemistry and radiology. This is actually part of medicine, medicine and allied health sciences here we have radio chemistry, body imaging and nuclear chemistry. So because nuclear medicine which is part of nuclear chemistry. All right coming over we have quantum mechanics, spectroscopy, material science and biomechanics. Now here this one is a little bit off from the other ones because it's so heavily math based. This is our friend physics. Next we have our physical sciences which is part of geology. Then we have ecology and pollution studies. So this is part of our environmental sciences. And then here move up one we have here botany and agronomy. So we're talking about agriculture here. So this would be our let's see. Plant sciences. So these would represent are different types of scientific disciplines which orbit are central science of chemistry. Now, of course, if you consult one of these other scientific disciplines that people majoring in them, they'll say no. They're the major part in everything has branches off of them, but just realize at the end of the day, they're all connected to one another.

Clutch Version GOB/Intro

The Density of geometric objects generally includes spheres, cubes and cylinders.&nbsp;

Density of Geometric Objects

Intensive Properties are independent and Extensive Properties are dependent on the size or amount of substance present

Intensive vs. Extensive Properties

A physical change involves a change in the phases of matter, whereas a chemical change involves a change in chemical bonds.&nbsp;

Physical & Chemical Changes

Chemistry is the science that deals with the composition, structural arrangement and properties of substances.

What is Chemistry?

Metric Prefixes are “labels” that can be placed in front of base units.&nbsp;

Metric Prefixes

Significant Figures are used to discuss the level of precision in any measurement.&nbsp;

Significant Figures: Precision in Measurements

Density represents the mass of an object or compound within a given volume.&nbsp;

Density

&nbsp;From the simplest view, Specific Gravity represents density without the units.&nbsp;

Specific Gravity

The International System of Units (SI) represents the modern form of the metric system.

SI Units (Simplified)

The Density of non-geometric objects can be determined using water displacement.&nbsp;

Density of Non-Geometric Objects

We use Dimensional Analysis&nbsp;as a fail proof process to convert from one unit to another.

Dimensional Analysis

The Scientific Method is a process used to help design and perform experiments in order to minimize experimental errors.

The Scientific Method

The number of Significant Figures for a value affects its precision.&nbsp;

Significant Figures (Simplified)

Chemistry is the study of matter and the changes it undergoes, with the atom being its basic functional unit.&nbsp;

Classification of Matter

Chemical Properties are observed during chemical reactions.&nbsp;

Chemical Properties

Conversion Factors are used to tie together 2 different units.&nbsp;

Conversion Factors (Simplified)

Significant Figures are often involved in mathematical calculations.&nbsp;

Significant Figures: In Calculations

Physical Properties are measurable properties that describe the state of chemical compounds.&nbsp;

Physical Properties

The 3 States of Matter include gases, liquids and solids.&nbsp;

States of Matter

Scientific notation is used&nbsp;to turn small or large&nbsp;inconvenient numbers into manageable ones.&nbsp;

Scientific Notation

Temperature is a measurement of how hot or cold a substance is based on its kinetic energy.
