Temperatures of four liquid substances are shown in the chart. A 2 column table with 4 rows. The first column is labeled substance with entries W, X, Y, Z. The second column is labeled temperature in degrees celcius with entries 40, 37, 19, 37. Which statement is best supported by the data in the chart?

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

Explanation:

Thermal energy moves from the warmer to cooler (that rules out B & C). Conduction is when molecules are in direct contact with each other whereas radiation involves electromagnetic waves (that rues out A).
