For experiment A, the hypothesis predicted the reaction would be
endothermic
. The temperature changed from
23
to
18
. Because the temperature
went down
, the reaction must be
endothermic
. The hypothesis was
by the data. Responses refuted and supported
Based on the given information, the hypothesis was supported by the data. The hypothesis predicted that the reaction would be endothermic, and the observed decrease in temperature from 23 to 18 supports this prediction.
The hypothesis, which predicted that the reaction would be endothermic, was supported by the data. The temperature decrease from 23 to 18 indicates that heat was absorbed or taken in by the system, which is consistent with an endothermic reaction. Therefore, the data supports the hypothesis.
