Describe what is meant by the term thermal equilibrium. Describe what is meant by the term thermal capacity.
Understand the Problem
The question is asking for definitions of two scientific terms: 'thermal equilibrium' and 'thermal capacity.' The user needs to explain these concepts in the context of physics, particularly relating to heat transfer and material properties.
Answer
Thermal equilibrium is having no heat exchange; thermal capacity is heat needed for temperature change.
Thermal equilibrium is when two objects are connected by a permeable barrier and have no heat exchange because they are at the same temperature. Thermal capacity refers to the amount of heat required to change the temperature of an object.
Answer for screen readers
Thermal equilibrium is when two objects are connected by a permeable barrier and have no heat exchange because they are at the same temperature. Thermal capacity refers to the amount of heat required to change the temperature of an object.
More Information
Thermal equilibrium is essential for understanding heat transfer and temperature control. Thermal capacity explains why different substances heat at different rates.
Tips
A common mistake is confusing thermal capacity with specific heat capacity. Thermal capacity is for the entire object, while specific heat capacity is per unit mass.
