Answer:
In the air
Explanation:
There are three states of matter:
- Solids: in solids, the particles are tightly bond together by strong intermolecular forces, so they cannot move freely - they can only vibrate around their fixed position
- Liquids: in liquids, particles are more free to move, however there are still some intermolecular forces keeping them close to each other
- Gases: in gases, particles are completely free to move, as the intermolecular forces between them are negligible
For this reason, it is generally easier to compress/expand the volume of a gas with respect to the volume of a liquid.
In this problem, we are comparing water (which is a liquid) with air (which is a gas). From what we said above, this means that the change in volume is larger in the air rather than in the water.
Answer:
A. False, frequency can increase or decrease wavelength.
For example: a high frequency would mean there are shorter wavelengths that occur in a period. Meanwhile, a low frequency would indicate that the wavelengths are longer and in longer periods.
Alright here the answer to number 2
Answer:
0.25 L
Explanation:
= Initial pressure = 1 atm
= Initial Temperature = 20 °C
= Initial volume = 4.91 L
= Final pressure = 5.2 atm
= Final Temperature = -196 °C
= Final volume
From ideal gas law we have

The pressure experienced by the balloon is 0.25 L
I believe the answer is 3). The cell wall provides protection, it doesn’t control movements of materials in and out of the cell.
