Question 41

A student dissolves ammonium nitrate in water and records the following results:

  • temperature of water at start = 22 ∘C22\text{ }^{\circ}\text{C}22 ∘C
  • temperature of mixture after stirring = 14 ∘C14\text{ }^{\circ}\text{C}14 ∘C

Explain, using these results, the type of energy change that occurs when ammonium nitrate dissolves in water.
