Using Gay-Lussac's Law, calculate what the new pressure in the following situation. A tank of acetylene sits on the back of a truck. During the afternoon, the temperature
of a gas has reached 38°C (311 K) with a pressure of 508 kPa. That night, the
temperature drops to 29°C (302 K). Since the gas was in a metal tank, the volume
remained constant. What is the new pressure?

Match the vocabulary terms to their definitions. 1 . a long, chain-like set of molecules made up of repeating units joined end to end polymer 2 . a hard, brittle, heat- and corrosion-resistant material made by subjecting a nonmetallic mineral mixture to intense heat ceramic 3 . a plastic with low elongations that cannot be recycled thermoset 4 . a carbon fiber embedded in a polymer resin matrix thermoplastic 5 . a plastic with high elongations that can be recycled crystal 6 . a solid form resulting from the arrangement of atoms, ions, or molecules in definite geometric patterns composite
