The correct option is (b) False

Easy explanation: The given statement is false. Relative to other forms of food packaging, glass has the least resistance to temperature changes. The resistance to thermal failure depends on the type of glass employed, the shape of the container and the wall thickness. When a glass container is suddenly cooled, tensile stresses are set up on the outer surfaces, with compensating compressional stresses on the inner surface. Conversely, sudden heating leads to surface compression and internal tension.
