Answer

Explanation:

Step1: Recall heat - transfer principles

Heat transfers from a higher - temperature substance to a lower - temperature substance. Conduction occurs when substances are in direct contact, and radiation can occur between non - touching substances.

Step2: Analyze option A

Substance X (37°C) has a lower temperature than substance Y (19°C) is incorrect as heat transfers from higher to lower temperature. So, this option is wrong.

Step3: Analyze option B

Substance Y (19°C) has a lower temperature than substance Z (37°C), so heat will transfer from Z to Y, not from Y to Z. This option is wrong.

Step4: Analyze option C

Substance X (37°C) has a lower temperature than substance W (40°C), so heat will transfer from W to X, not from X to W. This option is wrong.

Step5: Analyze option D

Substance W (40°C) has a higher temperature than substance X (37°C). When they are mixed (in direct contact), heat will transfer from W to X through conduction. This option is correct.

Answer:

Substance W will transfer thermal energy to substance X through conduction if they are mixed.
