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

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

A. 100 cm^3

B. 264 cm^3

C. 900 cm^3

D. 252 cm^3

Calculation:

We are asked to find the new volume of a gas when temperature changes at constant pressure. This is a Charles’s Law problem:

V1/T1 = V2/T2

Where:

• V1 = 300 cm³

• T1 = 60^0C = 60 + 273 = 333K

• T2 = 20^0C = 20 + 273 = 293K

• V2 = ?

Step 1: Apply Charles’s Law

V2 = V1*T2/T1

V2 = 300 * 293/333

Step 2: Calculate
293/333approx 0.879
V2 = 300 * 0.879 approx 263.7 approx 264 cm³

✅ Answer: B. 264 cm³
