bag of popcom into a microwave oven turn the oven on, and listen for the kernels to pop?
a.) electrical energy → thermal energy → nuclear energy
b.) electrical energy thermal energy →
mechanical energy
c.) thermal energy → mechanical energy
chemical energy
electrical energy
d.) mechanical energy thermal energy

Answer 1

Answer: b) microwave energy causes water molecules to heat and vaporise, causing the expansion of the kernels, sound and movement which are all due to mechanical energy

Explanation: as above
