The price of the device has been steadily increasedâby 32 percent in the past year aloneâbut not because the cost of the raw materials was increasing (a typical dose of epinephrine still costs about a dollar). The profit margin of the EpiPen was 9 percent in 2008. Today itâs 55 percent.
Frost is a form of ice and can only survive at temperatures of 32 degrees Fahrenheit and below. But that doesnât mean the measured air temperature must be 32 or below for frost to form on a surface.
Frost or freezing occurs when the temperature of air falls below the freezing point of water (0 Â°C, 32 Â°F, 273.15 K). This is usually measured at the height of 1.2 m above the ground surface. There is a rather subjective scale to show several degrees of frost severity: 1  slight frost: 0 to â3.5 Â°C (32.0 to 25.7 Â°F) 2  moderate frost: â3.6 to â6.5 Â°C (25.6 to 20.3 Â°F) 3  severe frost: â6.6 to â11.5 Â°C (20.2 to 11.3 Â°F) 4  very severe frost: below â11.5 Â°C (11.3 Â°F)
