Question

In a cathode ray tube, electrons flow from the negatively charged cathode to the positively charged anode. Cathode ray tubes may be small and compact, but they typically must be plugged in to function. The flow of electrons within this tube is:________.

a. spontaneous

b. nonspontaneous

c. neither spontaneous nor nonspontaneous

d. impossible to tell

Answer 1

Answer:

spontaneous

Explanation:

Electrons in a cathode ray tube are produced at the cathode and move towards the anode which is the the positive electrode.

This flow of electrons is spontaneous because electrons flow from a point of negative electric potential to a point of positive electric potential, hence the answer above.
