Question

5. A sealed syringe filled with air has a volume of 69 mL at 25°C. When the syringe is placed in a deep freezer the volume changes to 5.3 mL. What is the temperature in the deep freezer? Report finalayswer in degree Celsius. Assume all other conditions are kept constant. b pts

Answer 1

Charles law volume of a gas the absolute At constant pressure, the is directly proportional to temperature va T V=KT k is called constant final volumes ", u are the initial and respectively. Ty, ty are the initial and temperatures in Kelvin final

V = 6.9 ml at Ti= 25+273 = 298 K V2 = 5.3 ml at Ta= ? 6.9 ml 298k 5.3h 5.3 ml x 298K 6.9 ml T₂ = 2280898558 Ty = 228.8985-273 Ty = -44-10 14°C
