Alfred Nobel, a Swedish inventor, is best known for his invention of dynamite, which made him a wealthy man. In his will, Nobel specified that his fortune should be used to create prizes for outstanding achievements in various fields. The Nobel Prizes are awarded every year in five fields: Physics, Chemistry, Medicine, Literature, and Peace. The first Nobel Prizes were given out in 1901, and they have continued to be awarded annually since then.
Nobel was also a man of varied interests. In addition to his scientific work, he had a passion for literature. His wealth gave him leisure to write plays, novels, and poems, reflecting his creative side. Despite being known for his inventions, Nobel's wide range of talents suggests that he was independent and creative, always exploring new ideas and avenues of expression.
Nobel’s work with explosives began when he became interested in nitroglycerin, a highly volatile substance invented by Italian chemist Ascanio Sobrero. Although Sobrero created the explosive, it was Nobel who found a way to make it safer for use in industry. By stabilizing nitroglycerin, he was able to create dynamite, a safer and more controlled form of the liquid, which became widely used in construction and mining.
Which detail from the passage supports that he was independent and creative
a. “His wealth gave him leisure to write plays, novels, and poems.” b. “As a teenager, he showed a great talent for science.” c. “He had a tremendous energy for his work.” d. “He built factories in Germany, Sweden, New York, and California.”
a. “His wealth gave him leisure to write plays, novels, and poems.”
Dynamite is a highly powerful explosive used in construction and demolition projects. It has a quick reaction that releases a large amount of energy in a very short time. Materials like absorbent soil can be used around the blast site to help absorb shockwaves and minimize damage. The diameter of the blast area is carefully calculated to ensure safety and effectiveness when using dynamite. Which word used in Passage 1 has a science prefix meaning “across” A) absorbent B) diameter C) dynamite D) explosive
B) diameter
Before dynamite was invented, blasting through rock to build roads, bridges, and mines was a much slower and more dangerous job. Today, dynamite makes these tough construction tasks much faster, easier, and safer.
Dynamite is a powerful chemical explosive. It creates a huge rush of hot gas when ignited, producing enough pressure to break through even solid rock. Dynamite has been essential in building cities, roads, tunnels, and mines all over the world.
The key ingredient in dynamite is nitroglycerin, a highly explosive and dangerous chemical. To make it safer to use, the nitroglycerin is absorbed into a material that looks like sawdust. This mixture is packed into paper tubes about an inch wide and 8 inches long, and sealed with paraffin wax to protect it from moisture. Different sizes of dynamite tubes are made depending on the needs of a project.
Blasting experts must be very careful when using dynamite. For safety, the dynamite is transported in one truck, while the wires and firing switches are carried in a separate vehicle. This prevents accidents from happening before the dynamite is ready to be used.
Today, dynamite is only sold to licensed professionals who are trained to handle it. Because it is such a powerful and important tool, it must be used carefully and responsibly. Dynamite continues to help builders and engineers complete massive construction projects that would otherwise be impossible.
The word "dynamite" has even become a way to describe something exciting or impressive. So if someone calls you "dynamite," take it as a big compliment—you’re powerful and amazing!
What are two main ideas developed in Passage 1? A. Dynamite is a powerful tool used in the construction of roads, bridges, and mines. B. Dynamite is an explosive that uses a dangerous chemical called nitroglycerin. C. Dynamite is safe because its explosion creates a “cool flame.” D.
