Wave A has the shorter wavelength due too the fact that the shorter the wavelength the higher the frequency as they have an inverse relationship.
Answer:
I'm pretty sure the correct answer is b, I took this quite a while ago so I might not be right I would do some research about it. hope I helped!
Answer: -
If a gas at 250 K has a pressure of 0.00008 Pa and the pressure drops to 0.00002 Pa, 62.5 K is the new temperature
Explanation: -
Initial Pressure P₁ = 0.00008 Pa
Final Pressure P₂ = 0.00002 Pa
Initial Temperature T₁ = 250 K
Since the volume is not mentioned, it remains constant.
So initial Volume V₁ = Final volume V₂
Now using the combined gas equation
=
Final Temperature T₂ =
Plugging in the values,
T₂ =
As V₂ = V₁, they cancel each other.
T₂ = 62.5 K
A is correct. Potential energy decreases and turns into kinetic energy.
Explanation:
density = mass/volume
Acetone has density 0.784 g/ml
volume = mass/ density
Volume = 8.00/0.784
= 10.204 ml
The volume of 8.00g of acetone is 10.204 ml.
