What would cause a drink bottle to explode?

Rating: 100

Carbonated beverages in glass bottles may explode when temperature is abused. Heat can increase the internal pressure within a bottle to a pressure of 50 pounds per square inch (psi) at 75 degrees F and 75 psi at 100 degrees F. Temperatures of over 100 degrees are not uncommon in car trunks or un-shaded storage rooms. If the heat is combined with defects in the glass, spontaneous explosions may occur.
