1. a stream of water will bend toward a balloon that has been rubbed on a sweater to generate static charge. Which property of water is responsible for this behavior?
A. THE polarity of the water molecule
b. the ability of water to form hydrogen bonds with itself
c. the heat capacity of the water molecules
d. he ability of water molecules to form a repeating lattice structure ***
2. which of the following is true.
a. biased thinking promotes scientific ideas
b. open-mindedness restricts scientific thinging
c. creativitly fosters scientific discovery**
d. close-mindedness cultivates scientific exploration
#1 Really, lattices are found in crystals. (Plus, why would that be affected by a charged balloon?)
#2 C looks good to me.
Yes...
To get the answer to question 1, you will need some knowledge of the properties of water and the behavior of static charges. Rubbing a balloon on a sweater generates static electricity, which results in a buildup of electric charge on the surface of the balloon. The interaction between the charged balloon and the stream of water suggests that the water is being influenced by an electric field.
The correct answer to question 1 is A. The polarity of the water molecule. Water is a polar molecule, which means it has a slight positive charge on one end (the hydrogen end) and a slight negative charge on the other end (the oxygen end). When an electrically charged balloon is brought near the stream of water, the positive end of the water molecule is attracted to the negatively charged balloon, causing the water stream to bend towards the balloon.
To get the answer to question 2, you will need to understand the concepts of biased thinking, open-mindedness, creativity, and scientific discovery.
The correct answer to question 2 is C. Creativity fosters scientific discovery. Scientific discovery often involves exploring new ideas, thinking outside the box, and finding unique solutions to problems. Creativity allows scientists to approach questions and challenges in novel ways, leading to new discoveries and advancements in the field. Open-mindedness is also an important trait in scientific thinking as it allows scientists to consider diverse perspectives and evaluate evidence objectively. Biased thinking and close-mindedness, on the other hand, can hinder scientific progress by limiting the exploration of alternative explanations or by dismissing new ideas based on preconceived notions.
#1 - A. The polarity of the water molecule.
#2 - C. Creativity fosters scientific discovery.
At least you did something right.
