The Persian War

The Persian War began in the 6th century BC. They conquered many of the polis in Asia Minor and in the eastern Mediterranean. These cities rebelled against the Persians. The first Persian War ended when the hoplites defeated the Persians at the Battle of Marathon. King Xerxes I began the second Persian War but was defeated at the Battle of Salamis.

The Peloponnesian War

Under the leadership of Athens, many polis formed a union called the Delian League. The domination of Athens threatened other polis such as Sparta, which opposed the Delian League of Athens and its allies. The two sides fought against each other in the Peloponnesian War. Sparta won the war and became the leading polis.

Romantic Opera

Opera was very important during Romanticism.

The most important opera style was Opera Buffa. There are three important countries and composers associated with this era.

Italy: Giuseppe Verdi (1813–1904)

Although conservatory teachers considered him too old to be taught music, despite having accepted him, Verdi became one of the most successful opera composers of all time. Important Operas: Rigoletto, Baile de Máscaras (Un ballo in maschera).

• Single leader or dictator
• Corporate state

The Causes of World War II

The Second World War was a vast conflict fought in Europe, Asia and other parts of the world. It was a conflict between the Axis powers, led by Germany, Italy and Japan, and the Allied powers that included Britain, the USSR, France and (from 1941) the United States.

• The impact of World War I: the peace treaties: Germany lost territory, and its economy was damaged by the need to pay war reparations.

• The rise of fascism and nationalism: many people feared that there would be a communist revolution in their own countries, people considered that fascism and extreme nationalism were the most effective way to combat communism.

• The weakness of democracies: democracies like Britain and France wanted to avoid a new war at any

Nutrition: The Foundation of Health

1.1 Definition

Nutrition is the study of foods and their impact on our growth and well-being. It encompasses the behaviors and social factors that influence our food choices.

Foods provide us with energy (calories) and essential nutrients such as protein, fat, carbohydrates, vitamins, minerals, and water. Consuming a balanced diet provides the energy we need for daily activities, helps maintain a healthy weight, and reduces the risk of chronic diseases like diabetes and heart disease.

Metabolism: The Body's Energy Engine

2.1 Definition

Metabolism refers to the chemical processes that occur within living cells and organisms to sustain life. These processes involve breaking down substances to release energy and synthesizing... Continue reading "Understanding Nutrition and Metabolism: Essential Concepts for Health" »

Economic Activity

Economic activity is what humans undertake to acquire goods (products and services) that satisfy consumer needs.

Economic Goods

Economic goods are products and services generated by economic activity.

Products

Products are goods obtained directly from nature (e.g., fish) or transformed into something else (e.g., clothes, books). They can be classified by:

• Composition: They can be consumable (durable consumer goods, such as computers, or non-durable, such as pizza) or capital goods (tools).
• Function: They can be intermediate goods (wool produced by a sheep) or finished goods (the shirt made from this wool).
• Ownership: They can be private (belonging to people) or public (belonging to the state).

Factors of Production

Factors of production... Continue reading "Understanding Economic Activity: Sectors and Factors" »

Ej 11: Industrial Revolution

• Around 1830
• Two main characteristics: slow and partial
• Five causes of industrialization: low demand for industrial articles, lack of entrepreneurial spirit among the bourgeoisie, technological gap, shortage of raw materials, political instability
• Basic industrial sectors: mining, iron and steel industry, textile sector
• Concentrated in Catalonia: textile sector
• Transport: thanks to the law of highways
• First railways: Barcelona-Mataro, Madrid-Aranjuez
• Scarce due to reduced international demand
• Badly affected by the loss of American

• Thermal energy is the energy that is exchanged between two bodies or systems of matter that have different temperatures. Thermal energy is also exchanged when a body changes from one physical state to another.

• Kinetic energy (Ec) is the energy of a body in motion. It depends on the mass and the speed of the body.

• Potential energy (Ep) is the energy of a body determined by its position. It depends on the body’s mass and position

• Gravitational Potential Energy
• Elastic potential energy

• Electrical energy is energy produced by the movement of charged particles (electrons), due to a potential difference.

• Radiant energy is energy carried by the electromagnetic waves, such as light, radio waves, microwaves, X-ray or γ rays. It’s called radiation.
