Answer:
33.0 L
Explanation:
Step 1: Given data
- Initial volume of the balloon (V₁): 30.0 L
- Initial temperature (T₁): 25.00 °C
- Final volume of the balloon (V₂): ?
- Final temperature (T₂): 55.00 °C
Step 2: Convert the temperatures to the Kelvin scale
We will use the following expression.
K = °C + 273.15
T₁: K = 25.00°C + 273.15 = 298.15 K
T₂: K = 55.00°C + 273.15 = 328.15 K
Step 3: Calculate the final volume of the balloon
If we assume ideal behavior, we can calculate the final volume of the balloon using Charles' law.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 30.0 L × 328.15 K/298.15 K = 33.0 L
Physical change because it's only changing the shape of the gold.
