ReShayla was making pancakes and decided that she wanted hot syrup on her pancakes. As she poured the syrup into a bowl, it came out slowly. After she heated it in the microwave for a few seconds, she poured the syrup onto her pancakes and it came out quickly. Why did the syrup come out quicker after she warmed it up? a. Its surface tension decreased because the radiation from the microwave broke the intermolecular forces it had. b. The radiation from the microwave increased its viscosity by breaking the syrup's intermolecular forces. c. Its surface tension increased because the radiation from the microwave broke the intermolecular forces it had. d.
