Cryоpreservаtiоn is cruciаl tо mаintaining cell culture facilities since cells can change properties, senescence, and are more likely to become contaminated as the length of time in culture increases. Special freezing reagents like dimethyl sulfoxide (DMSO) are added to the cells before freezing to prevent ice crystals from forming, which would rupture the cell membrane and kill the cells. There are three distinct temperature regions in which cell suspensions exhibit different thermodynamic properties (above freezing, at freezing, and below freezing). A. Determine the change in enthalpy for 1mL of cell suspension initially at 37ᵒC that will be frozen in liquid nitrogen at -196ᵒC). The specific heat of cell suspension above freezing (-3ᵒC) is 1.0A cal/(gm*K). The specific heat of frozen cell suspensions is .5B cal/(gm*K). The specific latent heat of fusion for cell suspensions is (70+C) cal/gm. You may assume the density of the cell suspension in freezing media is uniform and 1.0D gm/mL B. If you need to cool 100 vials of cell suspension down to -196ᵒC within 24 hours, at what rate must heat be removed (in Watts) from the system if your tank is 90% efficient?
