PISA Competition - Question 6
During long-distance running, body temperature rises, and sweating occurs.
If runners do not drink enough to replace the water they lose through sweating, they can experience dehydration. Water loss of 2% of body mass or above is considered to be a state of dehydration. This percentage is labelled on the water loss meter shown below.
If the body temperature rises to 40°C and above, runners can experience a life-threatening condition called heat stroke. This temperature is labelled on the body temperature thermometer shown below.
Question 1:
A runner runs for one hour on a hot, dry day (air temperature 40°C, air humidity of 20%). The health dangers the runner encounters by running under these conditions is dehydration, and this is shown in the next table by the
Sweat volume
Body temperature
Water loss
Air Humidity
PISA Competition - Question 7
During long-distance running, body temperature rises, and sweating occurs.
If runners do not drink enough to replace the water they lose through sweating, they can experience dehydration. Water loss of 2% of body mass or above is considered to be a state of dehydration. This percentage is labelled on the water loss meter shown below.
If the body temperature rises to 40°C and above, runners can experience a life-threatening condition called heat stroke. This temperature is labelled on the body temperature thermometer shown below.
Question 2:
A runner runs for an hour on a hot and humid day (air temperature 35°C, air humidity of 60%) without drinking any water. This runner is at risk of both dehydration and heat stroke.
What would be the effect of drinking water during the run on the runner's risk of dehydration and heat stroke?
Drinking water would not reduce the risk of either heat stroke or dehydration.
Drinking water would reduce the risk of dehydration but not heat stroke.
Drinking water would reduce the risk of both heat stroke and dehydration.
Drinking water would not reduce the risk of either heat stroke or dehydration
PISA Competition - Question 8
A runner runs for an hour on a hot and humid day (air temperature 35°C, air humidity of 60%) without drinking any water. This runner is at risk of both dehydration and heat stroke.
What would be the effect of drinking water during the run on the runner's risk of dehydration and heat stroke?
The two rows of data in the next table that support your answer in question two are:
1 and 2
2 and 3
1 and 5
3 and 5
PISA Competition Question 9:
When the air humidity is 60%, the effect of an increase in air temperature on sweat volume, without drinking, leads to an increase in sweat volume. Select two rows of data from the table below to support this conclusion.
1 and 3
3 and 4
1 and 5
3 and 5
PISA Competition - Question 10
Based on the data shown in the next table, when the air humidity is 40%, what is the highest air temperature at which a person can run for one hour without getting heat stroke?
20°C
25°C
30°C
35°C
