Answer:
Pressurized gas
Explanation:
When we compress the gas, the volume occupied by a gas decreases, since the volume is inversely proportional to the pressure, the compression of the gas causes an increase in Pressure. The molecules not only collide with each other but also on the walls of the container.
Compressed gases can cause fires, explosions, low-oxygen atmospheres, exposure to toxic gases and the physical danger associated with high-pressure cylinders. Special procedures for storage, use, handling and disposal are required to ensure the safety of the researchers who use these chemicals and equipment. There are also risks associated with the gas pressure and the physical weight of the cylinder. A falling gas bottle can break containers and crush your feet. The cylinder can become a missile if the cylinder valve breaks.

Answer:
8000m/s
Explanation:
Speed is the measure of ratio of distance to time taken to cover that distance.
So speed of wave is calculated as the product of wavelength and frequency.
As the wavelength is given as 20 m and the frequency is given as 400 Hz, then the speed will be
Speed = wavelength × Frequency = 20 × 400
Speed of wave = 8000 m/s.
So speed of wave is 8000 m/s.
