Question

jodie has an unknown substance in a cup. she placed a thermometer in the cup and collected the data shown in the pictures below. what most likely caused the substance to be solid in the second picture? a. heat was somehow added to the substance. b. the thermometer changed the temperature of the substance. c. the substance underwent a chemical reaction. d. heat was somehow removed from the substance.

Explanation:

Materials typically change from liquid to solid (freeze) when heat is removed, lowering their temperature. A thermometer is for measurement and doesn't change substance temperature significantly. There's no indication of a chemical reaction, and adding heat would make it more likely to stay liquid or turn to gas.

Answer:

D. Heat was somehow removed from the substance.
