Chemistry
1 answer:
dalvyx [7]3 years ago

Answer:

c ) 29.4 psi

Explanation:

If the density of earth was twice than its actual density which is 5.51 g/mL, then at sea level the atmospheric pressure of earth in British units would be equal to 29.4 psi because increase of gravity, increase occurs in the atmospheric pressure.  If we double the gravity of earth by double of the earth density, so the weight of that same mass of air will be double which leads to the doubling of the atmospheric pressure at the sea level.

1.00 mole of an ideal monoatomic gas at STP first undergoes isothermal expansion so that the volume at b is 2.5 times the volume
MrRa [10]

Answer:

the pressure at c = 0.27 atm

Explanation:

Given that:

number of moles (n) = 1.0 moles

Value of gamma in the monoatomic gas (γ) = 5/3

During an isothermal expansion, the volume at b is = 2.5 times the volume at a ; this implies that:

V_b = 2.5 V_a

∴ To calculate  the pressure at c from a; the process is adiabatic compression; so we apply:

P_aV_a^\gamma=P_cV_c^\gamma

\frac{P_c}{P_a}=[\frac{V_a}{V_c}]^{(2/3)

\frac{P_c}{1.0 atm}=[\frac{1}{2.5}]^{(2/3)

P_c=0.27 atm

Thus, the pressure at c = 0.27 atm

Answer:

The correct answer is - so that other scientists can replicate the experiment and make sure the results are correct or to check accuracy.

Explanation:

The data and procudres are required to be recorded or noted correctly so the experiment and research can be replicate and tested for the accuracy of the experiment by other scientist and researcher.

Mandy also need to note procedure, data, variables and other data correctly for the testing the accuracy and replication of the experiment. The replication is essential to check if every thing is correct and result are error free.
