Is there a difference between tepid water and lukewarm water? Are the terms interchangeable?
There is no difference, thus the terms are interchangeable.
Tepid water consists of two parts cold water and one part boiling water, which renders a temperature of about 40 degrees Celsius, which is round about 105 degrees Fahrenheit.
Luke warm water is also considered in the same temperature range, which concludes that both are the same.
A quick test would be that the water to the touch should just be a bit warmer that normal body temperature and should not burn you
According to dictionary.com, tepid means:
1. moderately warm; lukewarm: tepid water.
2. characterized by a lack of force or enthusiasm: tepid prose; the critics' tepid reception for the new play.
Actually teped water in cooking is 105 degrees Fahrenheit if you were around 86 that’s probably not hot enough to actually activate yeast so it’s important to follow directions. And if you go too hot up can kill yeast when baking so yeah ummm do some research first. Source: my dads an executive chef for over 30 years I texted him to verify I had the info correct :) verified 👍
