Biology

Sublimation is caused by the absorption of heat which provides enough energy for some molecules to overcome the attractive forces of their neighbors and escape into the vapor phase. Since the process requires additional energy, it is an endothermic change.

What refrigerant safety group classification has the highest flammability and the highest toxicity?
timama [110]

Answer;

-B3

Explanation;

Refrigerants are divided into two groups according to toxicity:

-Class A signifies refrigerants for which toxicity has not been identified at concentrations less than or  equal to 400 ppm;  and

-Class B signifies refrigerants for which there is evidence of toxicity at concentrations below 400 ppm.

They are also divided into three groups according to flammability:

-Class 1 indicates refrigerants that do not show flame propagation when tested in air at 21°C and 101  kPa;

-Class 2 indicates refrigerants having a lower flammability limit of more than 0.10 kg/m3  at 21°C and  101 kPa and a heat of combustion of less than 19 kJ/kg;

-Class 3 indicates refrigerants that are highly flammable as defined by a lower flammability limit of less  than or equal to 0.10 kg/m3  at 21°C and 101 kPa or a heat of combustion greater than or equal to 19  kJ/kg.

-Therefore; the answer for the above question would be Class B and class 3.
