As a new firefighter you were given several old hydraulic manuals that were mimeographed from the 1920s. Over the years the manuals were exposed to air at room temperature and gradually turned yellow and the pages became brittle. The rate at which any change takes place depends on the temperature. Base on this which one is correct?

• The higher the temperature, the more rapidly the chemical change
• The higher the temperature, the more rapidly the physical change
• The lower the temperature, the more rapidly the chemical change
• The lower the temperature, the more rapidly the physical change
