What other substance (besides salt) could you sprinkle over ice to affect how fast it melts? Describe how you would test the substance's impact on the melting time of ice. Predict the results of such a test.
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.
