<span>When a sound wave reaches near the ear, the outer part of the ear acts like if its a funnel, so it catches the wave and funnels it into the ear. They the wave hits the eardrum. Then the bones in the eardrum cause each other to vibrate. Then they are sensed by nerves and sends signals to the brain to interpret sound. Hope This Helps!</span>
The pressure of a gas depends on the temperature and volume of the gas.
<h3>Ideal gas equation</h3>
PV = nRT
Where
- P is the pressure
- V is the volume
- n is the number of mole
- R is the gas constant
- T is the temperature
From the equation given above, we obtained the following:
PV = nRT
Divide both sides by V
P = nRT / V
R is constant and n = 1
P = T / V
Thus, we can see that the pressure (P) is dependent on the temperature (T) and the volume (V)

Answer:
mass (g) needed = 710.2 grams Na₂SO₄(s)
Explanation:
Needed is 2.5 Liters of 2.0M Na₂SO₄; formula wt Na₂SO₄ = 142.04g/mol.
mass (grams) of Na₂SO₄(s) = Molarity needed x Volume needed in Liters x Formula Wt of solute
mass (grams) of Na₂SO₄(s) = (2.5L)(2.0M)(142.04g/mol) = 710.2 grams Na₂SO₄(s)
Mixing: Transfer 710.4 grams Na₂SO₄ into mixing vessel and add water-solvent up to but not to exceed 2.5 Liters total volume. Mix until dissolved.
Gives 2.5 Liters of 2.0M Na₂SO₄(aq) solution.
