I2-10: DEWARS - SILVERED AND UNSILVERED
Additional Info
- ID Code: I2-10
- Purpose: Illustrate the function of silvering a dewar
- Description: Hot water is put into two dewars, one unsilvered and one silvered. The temperature of both in centigrade degrees is monitored as time passes; the photographs above show the temperatures immediately after the water is poured into the dewars and about thirty minutes later.
- Availability: Available
- Loc codes: I2, I0
