In the given sentences, the word "if" is used to express a condition or possibility, while the word "when" is used to indicate a specific time or situation. In the first sentence, "if" is used to express the condition that I might be late this evening. If that condition is true, then the person should not wait for me. In the second sentence, "when" is used to indicate that at some point in the future, I won't be able to see the person. In that situation, I will phone them. In the third sentence, "if" is used to ask for permission to close the window. It implies that I am unsure if the person minds me closing the window, so I am seeking their consent.
