Introduction
Dry ice, a solid form of carbon dioxide, is a fascinating substance with a unique lifespan that varies depending on several factors. Understanding the duration of dry ice can be crucial for safe handling, transportation, and effective use. This comprehensive article delves into the intricacies of dry ice's lifespan, providing valuable insights to ensure proper usage.
Factors Affecting Dry Ice Lifespan
The longevity of dry ice is influenced by various parameters, including:
Sublimation Rate and Lifespan Calculations
The sublimation rate of dry ice is typically expressed in pounds per hour (lbs/hr). This rate varies based on the factors mentioned above. For instance, at a temperature of -78.5°C (-109.3°F) and atmospheric pressure, dry ice sublimates at a rate of 5.1 lbs/hr per cubic foot.
Knowing the sublimation rate, the lifespan of dry ice can be calculated using the following formula:
Lifespan (hours) = Initial Mass (lbs) / Sublimation Rate (lbs/hr)
