Question

WILL NAME BRAINLYEST AND 60 POINTS Part 1: On Monday while Johnny was getting ready for school, he was in the bathroom holding his comb when he got an itch on his head. Johnny used the comb to rub his itch away and when he did his hair was a mess. He turned on the faucet so there was a small stream of water flowing and as he brought the comb near the water to dampen it, he noticed that the water was pulling towards the comb. Thinking he was seeing things, he pulled the comb back and the water was flowing straight down. He again moved the comb near the stream of water and the water again was pulling towards the comb. He repeated this process many times and the water continued to move towards the comb when the comb was near the water. What do you think is happening to the stream of water flowing from the faucet? Support you claim in Question 1, by explaining why you think it is happening. Formulate your hypothesis for the problem. Design an experiment to test your hypothesis. Part 2: Prior to science lab, Maria had been drinking a can of soda. When she walked into the lab she set it down on the hot plate at her station. She heard a liquid beginning to boil, and realized that the previous students had forgotten to turn off the hotplate and the boiling noise was from the remaining soda in the can. Without thinking, she picked up the can with her bare hands, and put it upside down into the sink which was half full of liquid. Immediately the can crushed as though it was going to be recycled. What do you think is happening to the soda and air in the can? Support you claim in Question 4, by explaining why you think it is happening. Formulate your hypothesis for the problem. Critique Maria’s laboratory safety procedures.

Answer 1

Answer:

It's mostly about surface tension. If you were to fill a glass with water so it goes over the top but doesn't overflow, the water bulges out over the top of the glass. When you pour water in a glass, it tends to stick to the sides of the glass (i.e. water droplets). The liquid is drawn toward the solid (i believe its because of the way the particles go but that's beside the point). So the water goes toward the comb because it's drawn to the solid.
