What other substance (besides salt) could you sprinkle over ice to affect how fast it melts? Describe how you would test the sub
Georgia [21]

Answer:

See explanation

Explanation:

Salt makes ice to melt faster than it usual. Sugar is another substance that influences the melting time of ice.

If i have a sample of pure ice and another sample of ice treated with sugar. I have to maintain the both initially at 0 degrees temperature and have a stop clock to measure the melting time.

I will ultimately notice that the sample of ice treated with sugar will melt faster than the pure sample of ice due to the presence of an impurity.

100 POINTS! HELP ME IF YOU LOVE JESUS!
mr Goodwill [35]
I only got 50 points (which is not 100). :-)

Look at the graph. At 80 °C, about 38 g of solute is able to dissolve, and that’s for ever 100 g of water. That means that for every 150 grams of water, 57 grams of solute can dissolve (38/2 = 19 + 38 = 57 g) at 80 °C. Since 57 g is greater than 55 g, all for he sodium chloride should dissolve in 150 g of water at 80 °C - you can put all of that into a “mathematical explanation”.
