Atomic bomb blasts in hiroshima and nagasaki
The atomic bombings of Hiroshima and Nagasaki in August 1945 marked the first and only use of nuclear weapons in war. The U.S. dropped atomic bombs called "Little Boy" and "Fat Man" on the cities, resulting in massive destruction and at least 200,000 immediate deaths from blast effects and radiation sickness. Long-term health effects persisted for decades, including higher rates of cancer, birth defects, and other issues. The bombings contributed to Japan's surrender and ended World War II, but also demonstrated the immense destructive power of nuclear weapons and their lingering effects on populations and the environment.

The atomic bombings of Hiroshima and Nagasaki in August 1945 resulted from Japan's refusal to surrender after the Potsdam Declaration. The US chose to use atomic bombs to avoid invading Japan, believing it would force surrender and save American lives. Hiroshima and Nagasaki were bombed, killing over 237,000 and 135,000 respectively from the explosions and injuries. Japan surrendered on August 14th, ending World War II.
Hiroshima august 1945
The United States dropped two atomic bombs on Japan in August 1945. The first bomb was dropped on Hiroshima on August 6th, killing around 90,000-166,000 people. The second bomb was dropped on Nagasaki on August 9th, killing around 60,000-80,000 people. In response to the bombings and the Soviet declaration of war, Japan surrendered on August 15th, officially ending World War II. The bombings led Japan to adopt a policy forbidding nuclear weapons.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help boost feelings of calmness, happiness and focus.

C20 Unit 1 3 Energy And Changes
There are three types of changes in matter:
1) Phase changes involve a change in state without a change in chemical composition, such as water changing between solid, liquid, and gas forms. Energy is absorbed or released during these changes.
2) Chemical changes involve a change in chemical composition, as seen through color changes, formation of solids/gases, or energy absorption/release. An example is the reaction of hydrogen and oxygen gases to form water.
3) Nuclear changes involve altering the composition of an element's nucleus through processes like fission, fusion, and radioactive decay. Energy is released or absorbed during these changes.
C20 Unit 1 2 Classification Of Matter
This document defines and classifies different types of matter. It describes elements as substances made of single atoms and compounds as bonded groups of elements. Pure substances include elements and compounds, while mixtures contain two or more substances mixed without chemical bonding. Mixtures can be homogeneous, appearing uniform, or heterogeneous, with distinct phases. Special types of mixtures include colloids, ores, alloys, and plated metals. The document provides examples to illustrate each classification of matter.
C20 Unit 1 4 The Periodic Table
- Mendeleev created the periodic table to organize elements based on similarities in their chemical reactions and properties.
- The periodic table is arranged in 18 vertical columns called groups and horizontal rows called periods.
- Elements are classified as metals, nonmetals, metalloids, or noble gases based on their physical properties such as appearance, conductivity, state of matter, and reactivity.
C20 Unit 1 1 Intro
Chemistry deals with the composition, properties, and interactions of matter, as well as energy changes. There are four main topics in chemistry - what matter is made of, how its particles are arranged, what characteristics it exhibits, and how it undergoes transformations through different types of changes including phase changes, chemical reactions, and nuclear reactions. Scientists make observations, which can be qualitative descriptions or quantitative measurements, to understand the physical and chemical properties of substances.
C20 Review Unit 02 Chemical Reactions
1) A chemical reaction can be differentiated from a phase change or nuclear change based on whether it involves a change in chemical composition, state of matter, or type of element.
2) In a chemical reaction, reactants yield products through the rearrangement of atoms. Chemical equations use symbols to represent the reactants and products.
3) Evidence that a chemical reaction occurred includes the release or absorption of energy, production of a gas, formation of a precipitate, or a color change.
C20 Review Unit 01 Matter Energy And The Periodic Table
This document provides an overview of key chemistry concepts including matter, energy, the periodic table, and changes in matter. It defines chemistry as dealing with what substances are made of, their properties, how they interact through chemical reactions, and related energy changes. Key terms like elements, compounds, mixtures, and properties are explained. The three main types of changes in matter - physical, chemical, and nuclear changes - are described along with examples. The periodic table is introduced and characteristics of different types of elements are outlined. Models of the atom and subatomic particles are summarized.
