Well, because solids are..solid. When you mix things together like to make a cake, the ingredients are either very small solids that dissolve or liquids.
Answer:
48 000 cm^2
Explanation:
8000 1cm cubes
each 1 cm cube side is 1 cm^2 and there are six sides to the cube , so each cube has 6 cm^2 surface area
and there are 8000 of them 8000 * 6 cm^2 = 48 000 cm^2
Answer:
The final temperature at 1050 mmHg is 134.57 
or 407.57 Kelvin.
Explanation:
Initial temperature = T = 55 = 328 K
Initial pressure = P = 845 mmHg
Assuming final to be temperature to be T' Kelvin
Final Pressure = P' = 1050 mmHg
The final temperature is obtained by following relation at constant volume
The final temperature is 407.57 K
Answer:
Cell Type I: Animal cell surrounded by a plasma membrane only.
Cell Type II: Plant cell surrounded by a plasma membrane and a cell wall.
Explanation:
Hello,
In this case, we must remember that animal cells are covered only by a plasma membrane, which is not enough to keep the cell from bursting as no limit for the inlet salt is established, causing it both to swell and burst. On the other hand, plant cells are covered by both a plasma membrane and a cell wall which contributive effect allow the inlet of the salt but prevent the cell to burst as the cell wall is rigid. In such a way, based on the described situation, one infers that the cell type I is an animal cell surrounded by a plasma membrane only the cell type II is a plant cell surrounded by a plasma membrane and a cell wall.
Best regards.
