Sentence: "If I were to win the lottery, I would travel the world."
Explanation: This sentence is in the conditional mood because it expresses a hypothetical situation. The use of "if" introduces a condition (winning the lottery) that is not guaranteed to happen. The phrase "I would travel the world" indicates the potential outcome that depends on the fulfillment of the first part of the sentence. The word "were" here is specifically a subjunctive form used to discuss unreal or contrary-to-fact situations, reinforcing the hypothetical nature of the conditional statement.
