A sampling rate is a term that is used in digital recording to describe how much, and how often, data is used. In digital audio (sound recording), a new sample of analog data -- a new speaker position -- is sent out to the speaker quite often, usually at a sample rate of 44100 Samples/second. So when the music is recorded for a CD, a new sample is collected from the microphones just as often, usually at a sample rate of 44,100 Samples/second. A biologist may measure the temperature of a lake once a week. That temperature data has a sampling rate is 1 Sample/week. Sampling rate is independent of "channels" or "bit resolution". A highly instrumented concert may have a dozen channels, each one from a microphone sampled at 44100 Samples/second, but the total sampling rate is still 44,100 Samples/second.
It stays the same. Temperature has no effect on the rate of nuclear decay.
for 4KHz then for noisy channel using Shannon theorem, sampling rate will be 8K samples/sec. So with 2 bit encoding, 2 bits are sent per sample. So the data rates is 8000 samples / sec * 2 bits = 16000bits / sec = 16kbps.
The higher the thermal energy of a diffused sample AND its solute, the faster the kinetic rate of motion of the dissolved particles, or atoms, and the faster their rate of diffusion throughout the solute.
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.

Standard audio CDs use a sample rate of 44.1 kHz, each sample has 16-bit resolution and there are two audio channels. 44,100 x 16 x 2 = 1,411,200 bits/s = 1,411 kbps. For comparison, the highest bit rate for MP3 is 320 kbps.
Unlike MP3 and WMA files, WAV files are not compressed, so they are not rated by bit rate (Mb/s). They are rated by sample rate, in samples per second. A high sample rate would be 96 kHz or 192 kHz. CDs have a sample rate of 44.1 kHz. In uncompressed audio, there is also the matter of bit depth, or resolution of the recording. CDs are 16-bit, but WAV files can be 24-bit or 32-bit.
CD quality refers to the amount of detail saved to an audio file that would be typical of what you would find on a CD. This is measured in how often a change in the sound wave is detected, known as the sample rate, and to what level of detail this change is measured to, known as the bit depth.Sample rate is measured in kilo-hertz (kHz), or thousand samples per second. For CDs this 44.1kHz.Bit depth is measured in bits, which is the number of binary digets each sample uses. For CDs this is 16bit.

In most recording programs, you are not recording directly to a compressed format (ie. one that describes the bit rate in kbps). Most are recording tracks in WAV or AIFF format, and each program has a method of setting the bit depth (16 or 24 bit) and sample rate (44.1 to 192 kHz). The compression to MP3, AAC, FLAC, OGG or other compressed formats happens after the recording, and you can choose the bit rate then. The calculation for kbps for CD quality (44.1 khz, 16 bit) is about 1411 kbps.
The standard CD is two-channel 16-bit PCM encoding at a 44.1 kHz sampling rate per channel.
It signals the difference between successive sample sizes
The sampling rate is the number of samples taken from a continuous signal over a period of time (typically measured per second - Sa/s or Samples per Second). The Nyquist - Shannon Sample Theorem states that a sample rate should be double the highest recorded frequency. Since the range of human hearing is 20Hz - 20,000 Hz, the minimum sample rate should be 40,000 Hz. CD format sample rates are 44.1kHz for this reason as well as other technical reasons.
