In the same sugar experiment, the mass that dissolves is 90 g at 20 °C, 110 g at 40 °C and 130 g at 60 °C for the same volume of water. Which conclusion fits the data?

Answer and explanation

Correct answer: A. In these trials, more sugar dissolved as the temperature rose.

  1. Step 1: The values rise from 90 to 110 to 130. Step 2. So higher temperature went with more dissolved sugar. Answer: In these trials, more sugar dissolved as the temperature rose. Why not the others: The data show a clear increase, a limit exists at each temperature, and volume was not varied.
