Explanation:
This is due to a reduction in atmospheric pressure – pressure due to the weight of the overlying air column). Remember that the higher the altitude the lower the air density and subsequently the lower the air pressure.
Therefore when heating water at higher altitude the vapor pressure of the water at the surface overpowers the atmospheric pressure – which is slightly lower than at sea level – even before the water temperatures reach 100 degrees centigrade.
The best answer here is B , i.e. the components of a homogenous mixture are evenly distributed
This means the constituents are mixed uniformly.
In a heterogeneous mixture, the constituents are not mixed uniformly.
Some good examples of a homogeneous mixture are:
1. Sugar solution
2. Soda
3. Water
5. soft drinks
6. Air
7. Vinegar
8. Brine
Some examples of a heterogeneous mixture are:
1. Blood
2. Milk
3.Water and oil
4. Water and sand
5. Soil
6. Hollandaise sauce
8. smog
