A thermocouple is submerged in water contained inside a beaker of 5.0 cm diameter and a height of 7.0 cm. An immersion heater with a maximum power of 300 W is used to heat the water to the set temperature of 80°C. Calculate the steady-state temperature error for values of DT of 3, 5, and 10. Assume that the convective heat transfer coefficient between the beaker and environment is h = 45 W/m2K and the environment temperature is 25°C.

Competing theories can be a source of new, testable ideas.

Explanation:

Theory is the set of knowledge that seeks to explain, with a high degree of accuracy, all-encompassing phenomena of nature, that is, it is different from the meaning of the word "theory" used in everyday life, when we say that something "is only a theory "in the sense that it is a mere speculation.

Competing theories present a much larger set of knowledge, which gives the universe a source of new and testable ideas
