Frage 6
Frage
A sample of expired air is collected in a gas jar. Another gas jar contains normal atmospheric air.
A lighted candle is placed inside each gas jar as shown. The time taken for each flame to go out is measured. As the candles burn they use up the oxygen available in the jar.
The table shows the results of this experiment.
The candle flame in jar X goes out in 15 seconds, while the candle flame in jar Y goes out in 9 seconds.
What is an explanation of the difference between the results in jars X and Y?
Image:
Q6 (binary/octet-stream)
Antworten
-
A Jar X contains atmospheric air which has more carbon dioxide.
-
B Jar X contains expired air which has more carbon dioxide.
-
C Jar Y contains atmospheric air which has less oxygen.
-
D Jar Y contains expired air which has less oxygen.
Frage 7
Frage
The diagram shows a section through an alveolus and a capillary.
Why does carbon dioxide move from X to Y?
Image:
Q7 (binary/octet-stream)
Antworten
-
A Air has a lower concentration of carbon dioxide than blood.
-
B Carbon dioxide moves more freely in air than in blood.
-
C Carbon dioxide must replace oxygen.
-
D Diffusion of carbon dioxide can only be out of the blood.
Frage 8
