Scientists make hypothesis in order to make an educated guess on the outcome of the experiment.
Answer:Entropy is defined as the measure of a system's thermal energy per unit temperature that is unavailable for doing work. The second law of thermodynamics states that the entropy of an isolated system never decreases over time
Explanation:
Entropy equal to change in mass divided by change in temperature
From above given M1 = 45.04g = 0.045kg
M2 = 35.04g = 0.036kg
T1 = -12.5oC, T2=100oC
Change in entropy of the system = (0.045 - 0.036)/ (100-(-12.5))
=0.009/112.5
=0.04
the fact that u would post ur whole test on here i see if u posting 3 but the whole test Girllllllllll
