14. Karim brings a chair from the backyard into his house and is going to stack it on top of another chair. Both chairs are the

same size and have the same number of molecules. The diagram above shows the chairs before they touch. Use the information in the diagram to answer the question.
How does the temperature of the bottom chair compare with the temperature of the top chair before the chairs touch? What will happen after the chairs have been touching for a while?

a Before the chairs touch, the bottom chair is cooler than the top chair. Once the chairs are touching, the top chair will transfer kinetic energy to the molecules in the cooler bottom chair until both chairs reach the same temperature, which will be in between their starting temperatures.

b Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the bottom chair will transfer kinetic energy to the molecules in the cooler top chair until both chairs reach the same temperature, which will be in between their starting temperatures.

c Before the chairs touch, the chairs are different temperatures. Once the chairs are touching, both kinetic energy and cold energy will transfer between the molecules in the two chairs until both chairs reach the same temperature, which will be in between their starting temperatures.

d Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the cooler top chair will gain kinetic energy until the molecules in both chairs have an energy of 35, because hotter things increase the temperature of cooler things.

Describe a semipermeable membrane.​
Sloan [31]

Answer:

A semipermeable membrane is a barrier that will only allow some molecules to pass through while blocking the passage of other molecules. A semipermeable barrier essentially acts as a filter. Different types of semipermeable membranes can block out different sized molecules. A semipermeable membrane can be made out of biological or synthetic material.

If not mistaken the answer should be, B, because when the body is dehydrated you get hot flashes which boosts you body temp and your bodily fluids decrease (thats why your mouth gets really dry) and your heart rate goes dangerously high. I hope that helps some, have a good day!!

Water is cohesive and adhesive
ValentinkaMS [17]
This dome-like shape forms due to the water molecules cohesive properties, or their tendency to stick to one another. Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to ability to form hydrogen bonds with one another
