Explain the quote 'Facts are not science — as the dictionary is not literature' by Martin H. Fischer in your own words and provide an example to illustrate the concept.
The quote implies that simply knowing facts does not constitute science, just as having a dictionary does not make one a literary expert. Science involves the application and interpretation of facts, similar to how literature involves the understanding and use of a dictionary. An example could be knowing the chemical composition of a substance without understanding its behavior in different conditions.
Describe the difference between physical and chemical changes of matter, and provide an example of each.
Physical changes involve alterations in the form or state of matter without changing its chemical composition, such as melting ice or dissolving sugar in water. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties, like the rusting of iron or the burning of a candle.
What is meant by a chemical reaction and how can we determine if one has occurred?
A chemical reaction involves the transformation of one or more substances into different substances with new properties. It can be identified by observing changes in color, temperature, formation of gas, or the production of a precipitate.
Explain the activity involving the burning of a magnesium ribbon and the observation made. What does this activity demonstrate about chemical reactions?
Burning a magnesium ribbon produces a bright white light and a powdery ash. This activity demonstrates the rapid combination of magnesium with oxygen in the air, forming magnesium oxide. It illustrates how chemical reactions involve the rearrangement of atoms to create new substances.
Provide an example from daily life for each of the following scenarios: milk left at room temperature during summers, iron tawa/pan/nail left exposed to humid atmosphere, and grapes getting fermented. Explain the changes that occur in each scenario.
Milk left at room temperature during summers can sour due to the growth of bacteria, leading to the production of lactic acid. Iron tawa/pan/nail left exposed to humid atmosphere can undergo rusting, forming iron oxide due to the reaction with water and oxygen. Grapes getting fermented involves the conversion of sugars in the grapes into alcohol and carbon dioxide by yeast, resulting in the production of wine or vinegar.
