Mr. Abersold informed his class that, under normal conditions, water boils at 100°C. He wanted to demonstrate that if the conditions change, water can boil at a lower temperature. Mr. Abersold used a hot plate to warm a beaker of water to 43°C. In step 1, he used a syringe to pull water out of the beaker. He made sure that the syringe was sealed and no air was inside. In step 2, he pulled up on the syringe plunger, which increased the space inside the syringe. When he did this, the water began to boil at 43°C, as shown in the image below.

What caused the water in the syringe to boil at 43°C?

OA. The air around the water started moving.

OB. The pressure on the water decreased.

OC. The thermal energy of the water increased.

OD. The water was put into motion by his hand.​
