Density

    This is a very basic question but I'm somehow not grasping this concept.. the question in my EK physics 1001 book is:

    A rigid container holds air (density 1.3 kg/m3) at 0 degree celcius. If the temp is increased to 273 degree celcius, what is the new density of the air?
    -The answer is that the since the volume and mass remained the same, so the density remains the same.

    I understand that logic can come from the p=m/v equation but I thought that if the temperature increases the density decreases because stuff expand when it's heated. Which is more correct?
