Outdoor decay of objects is a chemical reaction. Some ancient objects have been preserved extremely well in Arctic conditions. As glaciers have melted, archaeologists have discovered 4,000-year-old Viking clothing. Clarissa left her wool sweater outside at her family's summer cottage in Florida. When she returned the following summer, the sweater was in shreds, decayed by reactions that break down wool. Based on the data in the table, what can you conclude about the rate at which clothing decays in cold temperatures compared with the rate at which clothing decays in warm temperatures?
A. More information is needed to compare rates of decay
B. Reactions occur at the same speed in all temperatures
C. Reactions occur more quickly in the cold
D. Reactions occur more slowly in the cold.
