Answer:
V₂ =279.4 cm³
Explanation:
Given data:
Initial volume = 260 cm³
Initial temperature = 22.0°C
Final temperature = 44.0°C
Final volume = ?
Solution;
22.0°C (22+ 273 = 295k)
44.0°C(44+273 = 317k)
Formula:
According to Charles's law
V₁/T₁ = V₂/T₂
Now we will put the values in formula:
V₂ = V₁×T₂ / T₁
V₂ = 260 cm³ × 317k / 295k
V₂ = 82420 cm³. k / 295k
V₂ =279.4 cm³
