Water boils at 100oC at sea level pressure.
Select the situation(s) where water will boil at greater than 100 degrees Celcius.
Select one or more:
a.
Inside a pressure cooker.
b.
In Armidale, New South Wales (980 metres high).
c.
Inside an evacuated vacuum chamber where the pressure is 10−5 atmospheric pressure.
d.
In the eye of a cyclone or hurricane.
a. Inside a pressure cooker.
c. Inside an evacuated vacuum chamber where the pressure is 10−5 atmospheric pressure.
To select the situation(s) where water will boil at greater than 100 degrees Celsius, we need to consider the impact of pressure and altitude on the boiling point.
Based on this information, the correct options are:
a. Inside a pressure cooker: A pressure cooker increases the pressure inside the container, which raises the boiling point of water.
b. In Armidale, New South Wales (980 meters high): As altitude increases, the atmospheric pressure decreases, leading to a lower boiling point of water. Therefore, water will boil at a temperature higher than 100 degrees Celsius in Armidale.
c. Inside an evacuated vacuum chamber where the pressure is 10−5 atmospheric pressure: An evacuated vacuum chamber reduces the pressure to significantly lower than atmospheric pressure, resulting in a lower boiling point for water.
Therefore, options a., b., and c. are the situations where water will boil at greater than 100 degrees Celsius. Option d. is not correct since the eye of a cyclone or hurricane does not influence the boiling point of water.
