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? A. The thermal energy of the water increased. B. The pressure on the water decreased. C. The air around the water started moving. D. The water was put into motion by his hand.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
