Three samples of crystalline materials are available: sample A, B, and C. All of them are melted exactly at 82 degrees Celsius. Combine a mixture of sample A and B and melt at 82-degree Celsius. Next, combine a mixture of sample A and sample C and melt at 64-degree Celsius. Finally. Combine a mixture of sample B and sample C and melt at 71-degree Celsius. What can you determine about the samples A, B, and c?
