What is the relationship between pressure and temperature in the refrigeration cycle?

• Pressure has no effect on temperature

• High pressure causes refrigerant to evaporate

• Reducing pressure causes refrigerant to condense

• Pressure changes cause changes of state within the refrigerant

What is the function of the evaporator in the refrigeration cycle?

• To cool and condense the refrigerant gas

• To evaporate the liquid refrigerant into a gas

• To compress the refrigerant gas

• To restrict the flow of liquid refrigerant
