Understanding Energy Transformation and Its Impact on Climate Change

Questions: 30 | Attempts: 12 | Last updated: Aug 4, 2025

Sample Question
State that thermal energy may be completely converted to work in a single process, but that continuous conversion of this energy into work requires a cyclical process and the transfer of some energy from the system.

Thermal energy can be continuously converted to work without any additional steps.

The transfer of energy from the system is not necessary for continuous conversion of thermal energy into work.

Thermal energy may be completely converted to work in a single process, but that continuous conversion of this energy into work requires a cyclical process (thermodynamic cycle) and the transfer of some energy from the system (degraded energy).

Thermal energy can only be converted to work through irreversible processes.

Understanding Heat: Expansion, Contraction, and Temperature Measurement

Questions: 18 | Attempts: 23 | Last updated: Aug 4, 2025

Sample Question
Expansion is when...

An object remains the same size regardless of temperature changes.

An object absorbs heat. It increases in size (due to the increased space between particles. Thus, vol increasing and density decreasing.)

An object changes color when exposed to heat.

An object releases heat. It decreases in size.
