Answer:

The amount of the energy released at earthquake source.

Explanation:

Earthquakes are measured in two different ways.

  • Based on magnitude which is the amount of the energy released at earthquake source.
  • Based on intensity which is the quantification of how much of the ground shakes at the location.

Measurements on moment magnitude scale are determined using complex mathematical formula to convert the motion recorded with seismometer into the number which represents amount of energy released during earthquake.

9A. A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73
densk [106]

Answer:

351.43mL

Explanation:

To calculate the original volume of hydrogen gas in this question, the Boyle's law equation will be used. Boyle's law equation is:

P1V1 = P2V2

Where; P1 = initial pressure

V1 = initial volume

P2 = final pressure

V2 = final volume

According to this question, the P1= 1.56atm, V1 = ?, P2 = 0.73atm, V2 = 751mL

Hence;

P1V1 = P2V2

1.56 × V1 = 0.73 × 751

1.56 V1 = 548.23

V1 = 548.23/1.56

V1 = 351.43mL

Therefore, the original volume of hydrogen gas is 351.43 mL.
