In our lab‚ we were given the task of burning seven different salts and taking notes of what we observed. The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium

biology‚ geology etc.‚ deal with systems that seem to obey the laws of physics. According to Physics‚ the physical laws of matter‚ energy and the fundamental forces of nature govern the interactions between particles and physical entities (such as planets‚ molecules‚ atoms or the subatomic particles). Some of the basic pursuits of physics are describing the nature‚ measuring and quantifying of bodies and their motion‚ dynamics and so on. But what I want to touch up on is mass‚ force and weight.

Physics (from Greek φυσική (ἐπιστήμη)‚ i.e. "knowledge of nature"‚ from φύσις‚ physis‚ i.e. "nature"[1][2][3][4][5]) is the natural science that involves the study of matter[6] and its motion through space and time‚ along with related concepts such as energy and force.[7] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[8][9][10] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

What is Dalton’s Atomic Theory? Atomic Structure (Experimental Evidence for Atomic Structure): CH.2 [Section 1] 1. Circa 400-5 BCE (Greek Philosopher Democritus) a. Proposed the idea of matter being comprised of small‚ indivisible‚ indistructible particles (atomos) 2. Lavoisier (18th century) a. proposed the law of conservation of mass i. matter cannot be created or destroyed ii. atoms cannot be created or destroyed in a chemical reaction‚ they are simply rearranged to form new substances 3.

particular it is responsible for is beta decay. This happens when a neutron emits an electron and transforms itself into a proton‚ changing the atom into another element. The weak force thus demonstrates itself primarily through changes in particle identity‚ rather than particle motions. While the strength of the weak force is

these physicists impacted the development of the atomic theory one way or another. Albert Einstein was a German physicist who moved to America to share his knowledge about the atomic theory. In 1905‚ he wrote a famous paper that concerned tiny particles and how they moved in a liquid or gas. Einstein took Brownian motion(Browns law) and confirmed the atomic theory of matter by the use of Brownian motion. This was some of the first proof that atoms actually exist which is why most people say that
