Question

why does a pot of water boil at a higher temperature at sea level? select the best explanation. at sea level, the air pressure is lower, so the air exerts less force against the water in the pot. hence, the molecules of water must be at a lower temperature to have enough kinetic energy to change from a liquid to a gas (boil). at sea level, the air pressure is lower, so the air exerts less force against the water in the pot. hence, the molecules of water must be at a higher temperature to have enough kinetic energy to change from a liquid to a gas (boil). at sea level, the air pressure is greater, so the air exerts more force against the water in the pot. hence, the molecules of water must be at a lower temperature to have enough kinetic energy to change from a liquid to a gas (boil). at sea level, the air pressure is greater, so the air exerts more force against the water in the pot. hence, the molecules of water must be at a higher temperature to have enough kinetic energy to change from a liquid to a gas (boil).

Explanation:

When the air pressure is lower (at higher altitudes compared to sea level), water molecules need less kinetic energy to overcome the pressure and change from liquid to gas (boil). At sea level, air pressure is higher, so water molecules require more kinetic energy (higher temperature) to boil.

Answer:

At sea level, the air pressure is lower, so the air exerts less force against the water molecules of water must be at a lower temperature to have enough kinetic energy to change from a liquid to a gas (boil).
