### What does the half life of a radioisotope correspond to?

The length of time required for half of a sample of radioactive material to decay

### As the temperature of a radioactive sample increases the rate of the nuclear decay?

It stays the same. Temperature has no effect on the rate of nuclear decay.

### What does the half life of a radioisotope represent?

It tells what fraction of a radioactive sample remains after a certain length of time.

### If a half life is 2000 years will a large amount of this radioactive sample be around for a long time?

Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.Half-life of 2000 years means that after 2000 years, half of the sample will decay - so of course the other half of the sample is still around.
