A helium weather balloon is inflated so that the pressure inside is at Earth's atmospheric pressure (approximately 101 kPa). If the balloon is then released on a planet whose thick atmosphere results in a pressure inside the balloon twice that of Earth's atmospheric pressure, what will happen to the balloon's volume?
It stays the same.
It decreases slightly.
It increases slightly.
It halves.

- If you launch a projectile upward with a high enough speed, its kinetic energy is sufficient to allow it to escape the earth’s gravity— it will go up and not come back down. Given enough time, hydrogen and helium gas atoms in the earth’s atmosphere will escape, so these elements are not present in our atmosphere. Explain why hydrogen and helium atoms have the necessary speed to escape but why other elements, such as oxygen and nitrogen, do not.arrow_forwardThe absolute pressures in mercury at depths of 10 m and 8 m are found to be 100 MPa and 80 MPa, with a specific gravity of 13.6.

- Atmospheric pressure on Earth at its surface is 101 KPa (101 kilopascals or 101,000 N/m2). Which of these statements is true? If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will still be more than 1010 (10 billion) atoms per cm3 in the container. If we pump out the gas in a closed container leaving only 1 billionth of the original gas there will be fewer than 100 atoms per m3 in the container. When we reduce the pressure in the container while keeping the temperature constant, the number of atoms per m3 must stay constant. At 1 atmosphere, the number of atoms/m3 in air at room temperature is about 109, one billion atoms.arrow_forwardEstimate how many molecules of air are in each 2.0-L breath you inhale that were also in the last breath Galileo took.
