The temperature of the water in the first compartment of a 3-compartment sink depends on the purpose of the sink, but in culinary applications, it's usually around 110 to 120 degrees Fahrenheit (43 to 49 degrees Celsius).
Step-by-step explanation:
The temperature of the water in the first compartment of a 3-compartment sink depends on the purpose of the sink. In culinary applications, the first compartment is usually filled with warm water, typically around 110 to 120 degrees Fahrenheit (43 to 49 degrees Celsius). This temperature is ideal for washing and rinsing dishes and utensils, as it helps to remove grease and food particles effectively. However, it's important to follow local health and safety regulations, as these may specify the required temperature for the first compartment.
