With the rise of temperature, the velocity of sound:A. DecreaseB. IncreaseC. Remains the sameD. Is independent of temperatureE. None of these

As the temperature increases, the velocity of sound changes. To determine how it changes, we need to understand the relationship between temperature and the velocity of sound.

1. First, let's recall that sound is a mechanical wave that travels through a medium, such as air or water. The speed of sound in a medium depends on the properties of that medium, including temperature.

2. According to the general relationship between temperature and the velocity of sound, as the temperature of a medium increases, the velocity of sound also increases. This means that the correct answer is B. Increase.

3. The reason behind this relationship is that as the temperature rises, the molecules in the medium gain more kinetic energy and move faster. This increased molecular motion leads to a higher velocity of sound.

4. It is important to note that this relationship holds true for most common mediums, such as air and water. However, there may be exceptions in certain cases, such as in very specific conditions or with certain types of materials.

In conclusion, with the rise of temperature, the velocity of sound generally increases. Therefore, the correct answer is B. Increase.
