    1. The problem statement, all variables and given/known data
    a.) What are oils and fats that are solid at ambient temperatures?
    b.) What are oils and fats that are liquid at ambient temperatures?

    3. The attempt at a solution

    The questions give alternatives
    1. fatty oil
    2. ether
    3. margarine
    4. soap

    What determines if a oil/fat is solid or liquid? What is your reason for your "guess?" We can't help you until you show your work, not just guesses.

    Though, "ambient temperature" is a poor wording choice...that just means basically the temperature of the air around you, which could be anything from -40 C to +50 C (or more extreme) depending on where you live and what time of year it is. I assume the question means room temperature of about 23-25 C.

    I know that soap is solid in room temperature, while fatty oil like oil for food is liquid in room temperature.

    These are the reasons for my answers.
