🔥Exothermic process
  • Releases energy to the surroundings
  • Surroundings get warmer
  • Energy of products is lower
  • Often feels hot to the touch
  • Examples: freezing, condensation, burning
❄️Endothermic process
  • Absorbs energy from the surroundings
  • Surroundings get colder
  • Energy of products is higher
  • Often feels cold to the touch
  • Examples: melting, boiling, evaporation

Verdict

Exothermic processes give out energy and warm their surroundings; endothermic processes take in energy and cool them. The energy flow direction is the deciding factor.

Frequently asked

Is melting exothermic or endothermic?+

Melting is endothermic because it absorbs energy to break the solid structure.

Why does freezing release heat?+

As particles lock into a solid, they release the energy they held in the liquid state.

Does an exothermic process feel hot?+

Usually yes, because it releases energy as heat into the surroundings.
