    1. The problem statement, all variables and given/known data

    When a bicycle tire is filled early in the morning at 22 degrees C, the overpressure is 4.0 atm. What is the overpressure later in the day, when the temperature is 38 degrees C? Assume that the atmospheric pressure os 1.0 atm is constant.

    2. Relevant equations

    3. The attempt at a solution

    Please help.

    You have to tell us what you know about the relationship between pressure and temperature for a gas. Assume the gas is ideal and that the volume does not change.
