3. A sealed syringe contains 37.0 mL of trapped air. The temperature of the air in the syringe is the same as room temperature or 295 K. The Sun shines on the syringe causing the temperature of the air inside to increase. If the volume increases to 38.6 mL, what is the new temperature of the air in the syringe? (4 marks) V 1 = 37.0 mL = 0.037 L T 1 = 295 K V 2 = 38.6 mL = 0.0386 L T 2 = ? T 2 = V 2 T 1 V 1 = ( 0.0386 L) (295 K) 0.037 L = 308 K 4. The volume of a 1.5 L balloon at room temperature increases by 25 percent of its volume when it is placed in a hot-water bath. How does the temperature of the
