Question

Samuel forgot his sandwich on the counter at home. He went to school and when he returned home he saw his sandwich. He wanted to eat it but noticed the foul odor coming from his food. What factor probably contributed to his sandwich spoiling so quickly?

a. The physical change sped up when he cut his sandwich in half
b. The chemical change sped up when the temperature in his house decreased
c. The chemical change slowed down when the temperature in his house increased
d. The chemical change sped up in his house when the temperature increased

Answer 1

The quick spoilage of the sandwich was most likely due to a chemical change that sped up because of the increased temperature in Samuel's house, which led to a faster rate of spoilage. So the correcct option is d.

Step-by-step explanation:

The factor that probably contributed to the quick spoiling of Samuel's sandwich is the chemical change sped up in his house when the temperature increased. This is because chemical reactions, including those that lead to food spoilage, typically occur faster at higher temperatures. Therefore, if the temperature in Samuel's house was high while he was at school, this would have accelerated the spoilage process. In contrast, lower temperatures, as found in refrigerators, slow down these reactions, preserving food for longer periods.

Answer 2

With not knowing if the sandwich is wrapped in plastic or not, I will explain and tell the answer with that.

Explanation: When he got his sandwich from his house from the counter, the sandwich has no protective bag or plastic wrapped around it, with this, the bread, meat, and possibly other ingredients were exposed to flys, and roaches. Other than that, the bread would mold like the meat with the high temps, if there is, the lettuce had turned brown looked destroyed as it were dehydrated when lettuce has to stay cool and filled with its water not exposed to more warn elements than cool.

Answer: D: The chemical change sped up in his house when the temperature increased.
