What statement best explains why water boiled well below the boiling point in the boiling water demo?

• Ice water sped up the molecules of the water, lowering the volume of the water which allowed a lower boiling temperature.

• Ice water lowered the temperature of the gas, which slowed down the gas molecules, making them take up less space and finally lowering the pressure.

• The gas above the water created more pressure when the ice water was poured on it.

• The ice water lowered the pressure of the water. Allowing the water to boil at a lower temperature

Answer explanation

T lowered, V lowered, P lowered
