To classify the sentences based on whether they describe temperature or thermal energy, we need to understand the difference between the two concepts:
1. Temperature:
- It's a measure of the average kinetic energy of particles in a sample.
- It doesn't depend on the size of the sample.
Example: If you heat a small cup of water and a large pot of water to the same temperature, they will both have the same temperature, even though the amount of water in each container is different.
2. Thermal Energy:
- It's a measure of the total kinetic energy of particles in a sample.
- It depends on the size of the sample.
Example: If you have a small cup of water and a large pot of water at the same temperature, the larger pot of water will have more thermal energy because it contains more particles with kinetic energy.
By applying these definitions to the sentences provided:
- "It's a measure of the average kinetic energy of particles in a sample." describes Temperature.
- "It doesn't depend on the size of the sample." describes Temperature.
- "It's a measure of the total kinetic energy of particles in a sample." describes Thermal Energy.
- "It depends on the size of the sample." describes Thermal Energy.
This classification helps differentiate between temperature, which is about the average kinetic energy of particles, and thermal energy, which is about the total kinetic energy present in a sample.
