Helium has the lowest boiling point of the elements. The slightest change in temp can cause it to vaporize and expand. To prevent pressure explosions, a line from the tank has a "burst disk" in case a of sudden pressure increse. then the diaphragm would rupture and release the gas before pressure was too high. This is an example of which physics law? Boyle? Charles?
how come there is a blackout period when the space shuttle goes behind the moon? Is it because radio waves can be transmitted through a solid object or through a vacuum or why?
The space shuttle never goes behind the moon. It's not designed for lunar orbit. You're referring to the Apollo spacecraft.
Solid objects block electromagnetic waves depending on the wavelength. The earth and the moon block radio waves, which have a large wavelength.
The early Mercury spacecraft relied on stations around the world for communications. Mercury Control Center communicated with the remote stations using land lines.
The example you provided is related to Boyle's law, one of the fundamental gas laws in physics. Boyle's law states that, at a constant temperature, the pressure of a given amount of gas is inversely proportional to its volume. In other words, as the volume of a gas decreases, its pressure increases, and vice versa, as long as the temperature remains constant.
In the case of the helium tank with the burst disk, Boyle's law applies because the disk is designed to prevent pressure from building up to dangerous levels. The disk acts as a safety mechanism that releases the gas if the pressure inside the tank increases suddenly. The bursting of the disk allows the gas to escape, reducing the volume and thereby decreasing the pressure inside the tank. This action aligns with Boyle's law since pressure and volume are inversely related in a confined system with a constant temperature.
To explain how to get the answer, here are the key steps:
1. Understand the scenario and determine which gas law might be most applicable.
2. Recall the different gas laws, including Boyle's law and Charles's law.
3. Analyze the given information to find relationships between pressure, volume, and temperature.
4. Determine that the pressure-volume relationship fits Boyle's law.
5. Recognize that the burst disk in the helium tank functions to avoid pressure explosions by releasing excess gas and decreasing the volume.
6. Connect the actions of the burst disk with the principles of Boyle's law to conclude that the example demonstrates Boyle's law.
