Answer:
1.99 atm
Explanation:
Step 1:
Data obtained from the question. This include the following:
Initial pressure (P1) = 0.520 atm
Initial temperature (T1) = 26.2°C
Initial volume (V1) = 15.4L
Final temperature (T2) = constant = 26.2°C
Final volume (V2) = 4.02L
Final pressure (P2) =..?
Step 2:
Determination of the new pressure of the gas.
Since the temperature of the gas is constant, it means the gas is obeying Boyle's law. Thus, the new pressure of the gas can be obtained by applying the Boyle's law equation as shown below:
P1V1 = P2V2
0.520 x 15.4 = P2 x 4.02
Divide both side by 4.02
P2 = (0.520 x 15.4) / 4.02
P2 = 1.99 atm
Therefore, the new pressure of the gas is 1.99 atm
Answer:
The object with the greatest density
Explanation:
The object that will have the greatest mass from the given choices is the one with greatest density.
Density is the mass per unit volume of a substance;
Density =
We can see that density is directly proportional to the mass and inversely proportional to the volume.
The more the mass and the lesser the volume, the higher the density.
So, since the volume is the same, and mass is directly proportional to density, the object having the highest density will have the greatest mass.
