Markings to indicate length are placed on a steel tape in a room that is at a temperature of 20°C. Measurements are then made with the same tape on a day when the temperature is 14°C. Assume the objects you are measuring have a smaller coefficient of linear expansion than steel. Are the measurements too long, too short, or accurate?
