Metal contraction in freezer
Metal contraction in freezer
(OP)
I have two questions if I may
1-If an aluminum housing with a steel spool valve is placed in a freezer is it likely to be covered in frost on removal after several hours ?
2- Depending on the answer to (1) would this be a valid test for hanging spool valve when ambient temperature is cold?
Thanking you in anticipation

One more question if I may. Would placing the housing in the freezer while it is still warm encourage a coating of frost? I notice some aluminum housings do get covered in a light coating of frost while others do not.

The other mechanism for frost formation is having the object sitting outside in near-freezing temperatures but exposed to the night sky under clear conditions. Thermal radiation from the surface causes it to to below freezing and draw moisture out of the air and freeze it. Same thing can happen in the freezer if the conditions are right.
