What is the volume of a gas at 20^0C If its original volume at 60^)C is 300 cm^3? If the pressure is constant

What is the volume of a gas at 20^0C If its original volume at 60^)C is 300 cm^3? If the pressure is constant

A. 100 cm^3

B. 53 cm^3

C. 900 cm^3

D. 264 cm^3

Since the pressure is constant, we apply Charles’ Law:

V1/T1} = V2/T2

Step 1: Convert temperatures to Kelvin

• (T1 = 60^0 C = 60 + 273 = 333 , K)

• (T2 = 20^0 C = 20 + 273 = 293 , K)

Step 2: Substitute values

300/333 = V2/293

Step 3: Solve for (V2)

V2 = 300*(293/333)

V2=263.96 approx 264 cm^3

✅ Correct answer: D. 264 cm³
