Answer:
0.03 L
Explanation:
Step 1: Given data
- Initial volume of the balloon (V₁): 0.5 L
- Initial temperature of the balloon (T₁): 293 K
- Final volume of the balloon (V₂): ?
- Final temperature of the balloon (T₂): 20 K
Step 2: Calculate the final volume of the balloon
The balloon is filled with air. If we assume it behaves as an ideal gas, we can calculate the final volume of the balloon using Charles' law.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 0.5 L × 20 K/293 K = 0.03 L
Answer:
Change occur due to change in the state.
Explanation:
The model must be changed from the previous one because the liquid is exposed to high temperature which change the liquid into gaseous state. Due to change in the state from liquid into gas, the particles are present at more distance from each other because the gas molecules has more distance due to weak intermolecular forces so we can say that change must occur in the model.
