Supersonic aircraft fly at speeds greater than the speed of sound, known as Mach 1. This speed varies depending on altitude and atmospheric conditions but is approximately 343 meters per second at sea level. These aircraft can travel faster than ...

The velocity of sound in air increases with increasing temperature. This is because warmer air has more energy, causing air molecules to move faster and transmit sound waves more quickly.
Sound waves travel fastest in solids due to the dense molecular structure that allows efficient transmission of vibrations. In liquids, sound travels slower than in solids, and it is slowest in gases due to their sparse molecular arrangement. Sound cannot ...
The speed of sound in air at room temperature (20°C) is approximately 343 meters per second. Among the given options, the closest approximation is 330 meters per second. This speed can vary slightly with changes in temperature and atmospheric conditions.
Explosions are not heard on the Moon away from the surface Due to the absence of atmosphere. Sound requires a medium like air to propagate, and the Moon’s vacuum-like environment lacks air molecules necessary to transmit sound waves. Therefore, no ...
Humans feel sound vibrations in the frequency range of 20-20,000 Hz. This range encompasses the audible spectrum where human ears are sensitive to vibrations in the air, allowing us to perceive sound from low-pitched tones to high-pitched sounds like bird ...
The pitch of sound depends on Frequency. Pitch refers to the perceived highness or lowness of a sound, which correlates directly with its frequency. Higher frequencies create higher pitches, while lower frequencies produce lower pitches.
Ultrasonic waves cannot be heard by humans. They have frequencies higher than 20,000 Hz, beyond the range of human hearing. While some animals can detect ultrasonic frequencies, humans cannot perceive these waves audibly without the aid of specialized equipment.
A thermometer suitable for measuring 2000 °C is a total radiation pyrometer. These devices are designed to measure extremely high temperatures by detecting the thermal radiation emitted by an object, making them ideal for temperatures far beyond the range of ...
The heat required to convert a substance from liquid to gas without any temperature change is called latent heat of vaporization. This process occurs at the substance’s boiling point, where the liquid absorbs energy to overcome intermolecular forces and change ...
