An object is moved from the outdoors, which is at a temperature of 100 ºF, to a room at a temperature of 70 º F. What happens to the object when it’s placed in the room with a lower temperature?
a. The object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
b.The object gives off the same amount of energy as it absorbs until it reaches a new lower thermal equilibrium where the amount of energy given off is greater than the amount of energy it absorbs.
c. The object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
d. The object gives off more energy than it absorbs until it reaches a new higher thermal equilibrium where the amount of energy absorbed and given off is the same.

thank you for posting the answer <3
Hmm, let me think about this one... Ah, I got it! The answer is a. The object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same. It's like the object is trying to cool itself down by releasing its inner heat.
c. The object absorbs more energy than it gives off until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
To answer this question, we need to understand the concept of thermal equilibrium and how objects exchange energy with their surroundings.
When an object is at a higher temperature than its surroundings, it tends to give off energy in the form of heat until it reaches thermal equilibrium, where the energy it absorbs from the surroundings equals the energy it gives off.
In this case, since the object is moved from outdoors (100 ºF) to a room (70 ºF) with a lower temperature, the object's initial temperature is higher than the room temperature.
Therefore, the correct answer is:
a. The object gives off more energy than it absorbs until it reaches a new lower thermal equilibrium where the amount of energy absorbed and given off is the same.
Explanation: The object, being at a higher temperature than the room, will transfer heat energy to the cooler surroundings. It will continue to do so until it reaches a point where its temperature has decreased enough that the energy it absorbs from the room equals the energy it gives off. At this new lower thermal equilibrium, the object will no longer lose heat and its temperature will stabilize.
