Answer:
Interstellar Dust
Explanation:
In the solar system Interstellar dust is a type of cosmic dust and unlike Interstellar gas they have large dust particles enabling them to block visible light. Unlike smoke and fog, they contain large number of closely packed clumps of atoms and molecules
The difference in frequency of the two signals is 
.
The given parameters;

Answer:
24.24L
Explanation:
According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;
P is the pressure
V is the volume
k is the proportionality constant
PV = k
P1V1 = P2V2
P1 and P2 are initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?
From the formula;
V2 = P1V1/P2
V2 = 101×6/25
V2 = 24.24L
The final volume for the gas is 24.24L
