To analyze the statements based on the temperature data provided for substances W, X, Y, and Z:
- Substance W: 40°C
- Substance X: 37°C
- Substance Y: 19°C
- Substance Z: 37°C
Here's a breakdown of each statement:
-
Substance X will transfer thermal energy to substance Y mainly through radiation if they are mixed.
- Incorrect. The transfer would likely occur through conduction rather than radiation since they are in contact when mixed. Also, since substance X (37°C) is warmer than substance Y (19°C), thermal energy would flow from X to Y.
-
Substance Y will transfer thermal energy to substance Z through conduction if they are mixed.
- Incorrect. Substance Y (19°C) is cooler than substance Z (37°C), so thermal energy would flow from Z to Y, not the other way around.
-
Substance X will transfer thermal energy to substance W through radiation if they are placed near each other.
- Incorrect. While radiation could occur if they are not touching, substance W (40°C) is actually warmer than substance X (37°C), so thermal energy would flow from W to X if they were placed together.
-
Substance W will transfer thermal energy to substance X through conduction if they are mixed.
- Correct. Since substance W (40°C) is warmer than substance X (37°C), thermal energy would flow from W to X through conduction when they are mixed.
Based on the analysis, the statement best supported by the data is:
Substance W will transfer thermal energy to substance X through conduction if they are mixed.
