Question

Microwaves are sent through a material causing the molecules in the material to twist and vibrate, causing the material to heat up.
What is this twisting and vibration of the molecules creating heat an example of? (1 point)
a microscopic change creating a microscopic output
a microscopic change creating a macroscopic output
a macroscopic change creating a macroscopic output
a macroscopic change creating a microscopic output

Answer 1

a microscopic change creating a macroscopic output

Explanation: The microwaves cause molecular (microscopic) motion (twisting/vibrating), which produces heat you can feel/measure (a macroscopic effect).
