Physical And Chemical Changes During The Wattsamatta U?
346 Words2 Pages
Watching a smoothie being mixed, a pot of water boil, or, as we did in a mini-lab about water, watch ice melt, all represent physical changes. These changes are made when matter is separated, mixed, or moved by physical means. Another example of physical change is distillation, which we showed in a lab by boiling a green mixture to distill water from the substance. Physical changes normally take place with

Physical, Chemical And Nuclear Change In The Martian By Mark Watney
1472 Words | 6 Pages
In the book The Martian, Mark Watney survives on Mars due to the chemistry concept involving physical, chemical and nuclear changes, examples include him burning rocket fuel to make water and maximizing the use of his oxygenator and water reclaimer. Despite there being some other concepts that aided Mark in his survival, the way he understood physical, chemical and nuclear changes greatly increased his chances of living. To break it down, a physical change is any change in matter that involves a substance going from one state to another. A chemical change is when the substance is changed from its initial make up. Then, a nuclear change is when the nuclei can break apart to from a different element all together.
Empirical Formula Of Copper Chloride Lab Report
729 Words | 3 Pages
As the water was added to the heated sample, the solid copper chloride began to dissolve into a pretty blue-green solution, as a result of the compound breaking apart into individual Cu2+ and Cl- ions. When the water was first mixed with the copper chloride, it dissolved the solid pretty slowly, turning into a sort of mush at first. However, eventually, the water dissolved all of the solid copper chloride and the solution was homogenous. Since the compound just changed physical form, from solid to liquid, this change was purely physical. Just as in the first part of the experiment, the chemical character of the compound was not altered, so the compound did not experience a chemical change.

A phase of matter is a uniform with respect to both its physical and chemical properties. Matter undergoes phase transitions that change from one phase to another. A state of matter is a form that matter can take such as solids, liquids, gases, and even plasmas. There are some other states of matter that appear under extreme conditions but these are the main ones you use in your everyday lives. For example, imagine you have gatorade and water.

Gummi bears may not be obvious lab material, but in Mary Hershey’s chemistry class, they’re popular fodder for demonstrations. When they go up in flames, students are fired up—to the point of applause. Such displays help Hershey’s Chemistry 1 and Advanced Chemistry classes at State High understand concepts and connect with a challenging subject. “Just last week, we lit methane bubbles to teach them combustion,” Hershey said. “So you can teach chemical ideas through demonstrations, and when the demonstrations are in their head, you can draw on them to help teach and ask questions almost all year.”

AP Chemistry enthralled me with its indecipherable French theories and alphabet of Greek formulae, for my studies transmuted these into poignant prose. Information that had once seemed impossibly complex soon flowed from my mind as effortlessly as a pleasant conversation with a friend, and I began tirelessly consuming the material as though I had been starving for it. Cravings which had been subconsciously growing in me since childhood were relieved with a feast of answers: The fundamental concepts of existence revealed in a humble high school classroom. Soon, the only thing more insatiable than my curiosity was my ambition to apply this newly-acquired knowledge to the aching problems of the world. Studying the very building blocks of the universe

When acids are in rainwater and go onto the rock, this is an example of weathering. Weathering can also make mountains fall down/break apart. This is an example of mechanical processes can break the rock apart as these processes are governed by physical forces. Thermal expansion is an example of a mechanical weathering. As rock is exposed to sunlight during the day, it heats up and the heat causes it to expand.

“Woah,” I exclaimed as I observed the bubbles form in the cup that was in front of me. I had just combined Baking Soda and Vinegar, striving to understand the process of a chemical reaction. Later, I moved my attention to physics, where I was intrigued by the swinging pendulum in the grandfather clock that sat in the cozy living room of my small Michigan home. Little did I know that this was an epitome of simple harmonic motion. Although my observations did not allow me to comprehend the nature of a chemical reaction or the fundamentals of physics, they did spark a curiosity in my six year old mind that incited my passion for science.

Essay Determine Whether Three Separate Objects Of Different Colors And Shapes Are Made Of Same Materials
175 Words | 1 Pages
During this investigation determining whether three separate objects of different sizes, colors and shapes are made of the same materials. There was a grey cube, a cylinder and a silver cube. Based on the human’s vision, you can tell that the silver cube and cylinder are the most similar thus predicting that they are made of the same materials. Density was measured to help determine the similar in materials between each of the 3 objects. The density of a substance is the relationship between the mass of the substance and how much space it takes up.
