How did the presence of Charcoal Powder affect the sublimation rate of ice in vacuum experiments?

Answer

Higher concentrations led to a significantly higher sublimation rate.

Charcoal powder is strongly absorbing across the radiation spectrum; experiments showed that higher concentrations of charcoal powder resulted in a significantly increased sublimation rate compared to pure ice.
