Answer:
A more dense plate going underneath a less dense plate.
The molecules in gas are farther apart and have more room to bounce around than liquid
Answer:
0.73L
Explanation:
The following data were obtained from the question :
V1 = 0.65 L
P1 = 3.4 atm
T1 = 19°C = 19 + 273 = 292K
V2 =?
P2 = 3.2 atm
T2 = 36°C = 36 + 273 = 309K
The bubble's volume near the top can be obtain as follows:
P1V1 /T1 = P2V2 /T2
3.4 x 0.65/292 = 3.2 x V2 /309
Cross multiply to express in linear form as shown below:
292 x 3.2 x V2 = 3.4 x 0.65 x 309
Divide both side by 292 x 3.2
V2 = (3.4 x 0.65 x 309) /(292 x 3.2)
V2 = 0.73L
Therefore, the bubble's volume near the top is 0.73L
Scratching causes cracks and crevices on the surface of the flask (though microscopically). These will act as favorable sites for nucleation, which leads to the formation of crystals.
Answer:The solid is less dense than the liquid
Explanation:
Ice is less dense than water because of the crevices or spaces in the lattice structure of ice. Liquid water has a much greater density than solid water because its molecules are more compactly packed than in ice. Ice has large spaces between the hydrogen bonded water molecules hence less density than the liquid. Being less dense than !liquid water, it floats on water.
