Ice floats after it crystallizes because ITS DENSITY IS LESS THAN THAT OF WATER.
When a quantity of water is cools down by reducing its temperature, the molecules of the water lose kinetic energy and slow down in their movement. As the water is cooling down, it is volume is expanding. When the temperature reaches zero degree Celsius, the water becomes ice. At this point, the ice can float on water because its density is less than that of water; this is as a result of the spaces that now exist in the ice structure.
The first one is Solid, or A.
The second: B or liquids.
Third: also B I think.
Hope this helps.
Answer:
1200 mL
Explanation:
Given data
- Initial pressure (P₁): 600.0 mmHg
- Initial volume (V₁): 400.0 mL
- Final pressure (P₂): 200.0 mmHg
For a gaseous sample, there is an inverse relationship between the pressure and the volume. If we consider the gas as an ideal gas, we can find the final volume using Boyle's law.
Inhales. Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. Digestive System gets nutrients from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.
I hope this helps! :')
I might be a little late to answer your question. I'm sorry!
