Discussion Overview
The discussion revolves around the theoretical concept of mercury existing as a plasma at a temperature of 150 Kelvin, particularly in the context of a proposed engine design. Participants explore the implications of pressure and temperature on the state of mercury, questioning the validity of the claims made about its plasma state at such low temperatures.
Discussion Character
- Debate/contested
- Technical explanation
Main Points Raised
- One participant questions whether pressurizing mercury to 250k atmospheres could allow it to form a plasma at 150 Kelvin, suggesting this contradicts the typical understanding of plasma formation requiring high temperatures.
- Another participant emphasizes the need to clarify the source of the information regarding mercury plasma, implying skepticism about its validity.
- A participant asserts that mercury would be solid at 150 Kelvin, referencing its phase diagram and noting that it would have low vapor pressure, making evaporation unlikely without significant heating.
- Some participants argue that if mercury is at 150 Kelvin, it is likely solid, and thus cannot be a plasma unless it is super-heated, challenging the notion that pressurization could change this state.
Areas of Agreement / Disagreement
Participants generally disagree on the possibility of mercury being in a plasma state at 150 Kelvin, with some asserting it is solid and others questioning the definitions and parameters that could affect plasma formation.
Contextual Notes
There are unresolved questions regarding the definitions of plasma and the specific conditions under which mercury could transition to a plasma state, including the roles of temperature and pressure.
