A the answer is A I'm sure
Answer:
27.2atm
Explanation:
Data obtained from the question include:
V1 (initial volume) = 27.2mL
P1 (initial Pressure) = 1atm
V2 (final volume) = 1mL
P2 (final pressure) =?
Since the temperature is constant, the gas is obeying Boyle's law.
Mathematically, Boyle's law is expressed as:
P1V1 = P2V2
1 x 27.2 = P2 x 1
P2 = 27.2atm
The final pressure is 27.2atm.
Therefore, the pressure needed to compress the gas is 27.2atm
I’m pretty sure D transverse
Answer:
See explanation below
Explanation:
Water has the anomality of having the solid less dense than the liquid state. The reason for this is that the hydrogen bonds in the solid ice forces the molecule to occupy more room to properly have the stability afforded by the hydrogen bonds. That is the reason why ice floats on water.
The other interesting consequence of this anomality is that the slope of the solid/liquid phase boundary is negative since at higher pressures the ice can be changed to its liquid phase which can be seen from the negative slope of the solid/liquid boundary.
A) True
B) False
C) False
D) True
E) False
F) True close up to 4 ºC when the water molecules start to behave like other liquids, that is the density of the liquid decreases.
G) True
H) True ( repeated question)
Answer:
Here's what I find.
Explanation:
Many scientists contributed to our model of the atom.
Among those who received the Nobel Prize for their work are:
1906 — J.J. Thomson — discovery of the electron
1908 — Ernest Rutherford — nuclear model of the atom
1922 — Niels Bohr — planetary model of the atom
1922 — Albert Einstein — quantum mechanical model of the atom
1935 — James Chadwick — discovery of the neutron
