Answer the following question given this paragraph: How do you cool down a glass of room-temperature cola? You probably add ice cubes to it, as in the Figure below . You might think that the ice cools down the cola, but in fact, it works the other way around. The warm cola heats up the ice. Thermal energy from the warm cola is transferred to the much colder ice, causing it to melt. The cola loses thermal energy in the process, so its temperature falls. Q: What type of energy from a warm cola results in melting when it is transferred to the much colder ice? Choices: - protective energy - gaseous energy - cyclic energy - thermal energy A:
(Answer)
thermal energy

Ques:Answer the following question given this paragraph: We learned in the previous concept, "Scientific Explanations and Interpretations," that the average global temperature has been on the rise. Scientists know that carbon dioxide is a greenhouse gas . Greenhouse gases trap heat in the atmosphere. This leads us to a question:. Q: Where do greenhouse gases trap heat? Choices: - ground - space - altitude - atmosphere A:

Ans:
