(Short Answer) To protect their crops during freezing temperatures, orange growers spray water onto the trees and allow it to frees. In Terms of exothermic and endothermic changes, explain why this practice protects the oranges from damage. Exothermic=released energy and Endothermic=requires energy.....Freezing is exothermic. When the oranges are frozen, the energy will stay in the orange and it will stay warm.
