Options
- A. 566 mL
- B. 450 mL
- C. 350 mL
- D. 293 mL
Answer
D. 293 mL
Step-by-step solution
According to Charles's Law, at constant pressure, V_1 T_1 = V_2 T_2 Given: V_1 = 283 mL T_1 = 10\,^ C = 10 + 273 = 283 K T_2 = 20\,^ C = 20 + 273 = 293 K Substituting the values: 283 283 = V_2 293 V_2 = 293 mL Answer: 293 mL
