Systemic lupus erythematosus (SLE) is a chronic, often life-long, autoimmune disease. It can be mild to severe, and affects mostly women. SLE may affect various parts of the body, but it most often manifests in the skin, joints, blood, and kidneys.
When ice cream's small ice crystals melt and refreeze, they can turn into large, unpalatable lumps. Ice cream is best when stored between -5 and 0Â°F.; it will be firm enough to hold its shape, but easy to dip between 6 and 10Â°F, the ideal serving temperature range. Store ice cream in the main part of the freezer, not in the door where it is subject to more fluctuating temperatures.
The solution to Problem 49 shows that to make homemade ice cream, temperatures ranging downward from -3Â°C are needed. Ice cubes from a freezer have a temperature of about -12Â°C (+10Â°F), which is cold enough, but contact with the warmer ice cream mixture causes them to melt to liquid at 0Â°C, which is too warm.
