Question
Flori has one bucket of paint outside and one bucket of paint in her garage. Both paint buckets are the same size and have the same number of molecules. She brings the bucket in from outside and is going to stack it on top of the bucket in the garage. The diagram above shows the buckets now, before they touch. Use the information in the diagram to answer the question.
How does the temperature of the garage bucket compare with the temperature of the outside bucket before the buckets touch? What will happen after the buckets have been touching for a while?
Responses
a
Before the buckets touch, the two buckets are different temperatures. Once the buckets are touching, both kinetic energy and cold energy will transfer between the molecules of the two buckets until both buckets reach the same temperature, which will be in between their starting temperatures

Before the buckets touch, the garage bucket is hotter than the outside bucket. Once the buckets are touching, the cooler outside bucket will gain kinetic energy until the molecules of both buckets have an energy of 18, because hotter things increase the temperature of cooler things.

To determine the correct response, we need to analyze the situation based on common concepts in thermodynamics regarding temperature and kinetic energy transfer:
1. **Initial Temperature Comparison**: Often, the temperature inside a garage tends to be warmer than the temperature outside. Therefore, we would expect the garage bucket to be at a higher temperature than the outside bucket.
2. **Heat Transfer**: According to the second law of thermodynamics, heat (or thermal energy) will flow from the hotter object (the garage bucket) to the cooler object (the outside bucket) until both reach thermal equilibrium (the same temperature).
Given these principles, we can evaluate the response options:
- **Option a** states that both buckets are different temperatures but does not specify which is hotter, and it doesn’t accurately describe which way the energy will transfer.
- **Option b** incorrectly claims that the garage bucket is hotter than the outside bucket (not necessarily) but describes the thermal energy transfer correctly.
- **Option c** states that the garage bucket is cooler than the outside bucket, which contradicts the expected situation since typically the garage is warmer than outside.
- **Option d** accurately states that the garage bucket is hotter than the outside bucket and describes the transfer of kinetic energy from the garage bucket to the outside bucket correctly.
Thus, the right answer would be **Option d**:
"Before the buckets touch, the garage bucket is hotter than the outside bucket. Once the buckets are touching, the garage bucket will transfer kinetic energy to the molecules in the cooler outside bucket until both buckets reach the same temperature, which will be in between their starting temperatures."
