| 1. What
would you expect to happen in the test tube containing lime water? |
|
| 2. What
does this observation tell us about the yeast in the test tube? |
|
The number of bubbles of gas were
counted. This was done with the water bath at six different
temperatures. The temperatures and the results are shown below:

3. Plot a graph of
these results |
|
| 4. What
do the results show? (State your observations.) |
|
| 5. Why
do you think that the yeast in the test tube produces less and less
bubbles of gas as the temperature rises above 40°C? |
