too slow at taking temperature ? |
|
|
Everyone agree to be more alert,
evergone can see the stopwatch, counted out loud 10 sec before
the next minute. |
|
|
|
Thermometers not accurate in
reading? |
|
|
Checek the thermeters with same
reading. |
|
|
|
Temperature of CO2
lower than air at start of experiment? |
|
|
Ensure that the inside of the
bottle containing air is wet too. |
|
|
|
Difficult to read temperature
because of fogging inside the bottles? |
|
|
Turn the bottle to a clearer
area and try as best as one could to take the reading. |
|

there is wind? |
|
|
Put the bottles in a box, close
windows and door, minimise movement around the experiment. |
