Question

Which of the following questions is best considered as scientific? A. Who invented electricity?
B. How did dinosaurs live on earth?
C. How many koala are there in Australia?
D. Does the amount of water and salt affect the temperature at which it boils?

Answer 1

Answer:

a)Benjamin Franklin

b) Dinosaurs lived on all of the continents. ... During the 165 million years of dinosaur existence this supercontinent slowly broke apart. Its pieces then spread across the globe into a nearly modern arrangement by a process called plate tectonics.

c) The Australian Koala Foundation estimates that there are less than 100,000 Koalas left in the wild, possibly as few as 43,000.

d) Adding salt to water results in a phenomenon called boiling point elevation. The boiling point of water is increased slightly, but not enough that you would notice the temperature difference. ... Basically, the amount of salt people add to water for cooking doesn't affect the boiling point at all.

Answer 2

The following questions are best considered as scientific options:

D. Does the amount of water and salt affect the boiling point?

• Yes, salt increases the boiling point, but not too much.
• If you add 20 grams of salt to 5 liters of water, instead of boiling at 100 ° C, you will boil at 100.04 ° C.
• So a large spoonful of salt in a pot of water will increase the boiling point by four hundred degrees!
• To find out how table salt affects boiling water temperature.
• Salt when added to boiling water will make it boil at high temperatures.
• Boil one liter of distilled water.
• When water boils, measure its temperature.
• Include the reading of the highest temperature.
• This will be the control.
• As the deepwater begins to boil at temperatures above 212 and is pushed upwards, the water in the column quickly turns to steam and releases a column - at least what the park rangers describe as they seem to say. .
