Spontaneous

The video tutorial explains spontaneous processes on different scales. On a large scale, events like spontaneous combustion appear random but are often due to hidden factors such as heat buildup. On a subatomic scale, processes like radioactive decay are genuinely random.

What is often the cause of apparent spontaneity in large-scale events like spontaneous combustion?

• True randomness

• Hidden factors such as heat buildup

• External interventions

• Chemical reactions

Which of the following is an example of a large-scale spontaneous event?

• Radioactive decay

• Spontaneous combustion

• Photosynthesis

• Evaporation

What characterizes spontaneous processes on a subatomic scale?

• External influences

• Predictable patterns

• True randomness

• Controlled conditions

Which process is an example of a subatomic spontaneous event?

• Condensation

• Melting

• Radioactive decay

• Combustion

What is a common factor in both large-scale and subatomic spontaneous processes?

• External control

• True randomness

• Hidden factors

• Predictability
