Answer:
The volume of the gas will be 573.52 mL.
Explanation:
Boyle’s law states that <u>the pressure of a fixed amount of gas at a constant temperature is inversely proportional to the volume of the gas</u>.
The equation for Boyle's law is:
P₁V₁ = P₂V₂
We want to know V₂, that is, the volume of the container after the compression. We rearrange the equation and calculate:
V₂ = P₁V₁ ÷ P₂
V₂ = 1.14 atm × 815 mL ÷ 1.62 atm = 573.52 mL
Answer:
When we kick the ball, the force we apply to it causes it to accelerate from a speed of 0 to a speed of dozens of kilometers per hour. When the ball is released from the foot, it begins to decelerate (negative acceleration) due to the force of friction that is exerted upon it (as we observed in the previous example).
Explanation:
Answer:
c
Explanation:
the oxygen in the air and water from the rain caused oxidation causing the copper wire to become tarnished.
Answer:
Calcium carbonate
Explanation:
Ionic compounds that tend to have one or more polyatomic ions are the ones that tend to exhibit both ionic and covalent bonding. The only one that meets this is calcium carbonate.
By studying seismic waves
Explanation:
Scientists discovered that the earth's outer core is liquid by simply studying seismic waves.
Seismic waves are elastic waves that have been used by geophysicists to study the earth's interior.
- Interior of the earth is inaccessible due to high pressure and temperature conditions therein.
- To study this part of the earth, an indirect method should be used.
- Seismic waves produced during an earthquake due to their permeating nature have been used to study the interior.
- Seismic P-waves can pass through any materials because they are longitudinal waves. They go through solids, liquids and gases.
- S-waves can only pass through solids and not fluids.
- On a seismograph, it was discovered that the S-waves were cut off in a part of the reading.
- The waves re-appeared after a distance.
- Since S-waves cannot pass through liquids, it has been hypothesized that the outer core is liquid.
