Question

I conducted an experiment. I filled three cups with the exact same amount of water in them. Cup 1 has hot water. Cup 2 has room temp. water. Cup 3 has cold water. I took each cup and put one teaspoon of sugar inside of each. I timed how long it would take to completely dissolve the sugar in each cup. Would you think it would take more than 2 minutes, exactly 2 minutes or less than 2 minutes for each cup? Explain your reasoning using the four ideas of particle theory.

Answer 1

Given,

Amount of water = 200 mL

Percolation time = 40min

Rate of percolation = Amount of water in mL / Percolation time in min

=200 / 40

=5 mL/min.

Hence, the rate of percolation of water through the given soil sample is 5 mL/min.
