Question
At high altitudes, water boils at a lower temperature because
A.
the atmospheric pressure is high at high altitudes
B.
the viscosity of water is reduced at high altitudes
C.
the atmospheric pressure is low at high altitudes
D.
the surface tension of water is reduced at high altitudes.
Answer :
the atmospheric pressure is low at high altitudes
Solution :
At high altitudes, atmospheric pressure is low, hence water boils at a lower temperature.
