Fo value provides lethal equivalence between expected and practical conditions for autoclaving and can be expressed as…..Where,  Δt – the time interval between two temperature readings, T – the temperature at time t of the product under sterilization, z – temperature coefficient (assumed as 10 oC)

A test of the effectiveness of a thermal sterilization process uses a calculated F-value to determine which of the following? A. thermal death time B. the presence or absence of endotoxin C. disinfectant efficacy D. heat distribution factor

The Del factor for heating and cooling is 1.05 and 1.6 respectively. The initial no. of microbes before sterilization is 2.6x1016 .Calculate Holding time if k is 2.55 min-1

4. As bulas de testes de laboratório têm uma infinidade de especificações e indicações de uso, assim como o teste rápido de antígeno. Sendo assim, qual é a temperatura ideal de armazenamento do teste?A. Entre 2 e 30°C.B. Congelado. C. Entre -2 e -8°C.

18.State a control variable if you're investigating the effect of temperature on the time taken for iodine to remain yellow.

6. Convert the temp of the coldest area in a freezer, -10oF to oCa. 75.6 oCb. 12.22 oCc. 23.33 oCd. -23.33 oC
