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 ...
