Electrostatic interference can be nullified by A. connecting the thermocouple ground to the positive side of the junction. B. twisting and grounding the thermocouple wires. C. shielding and grounding the signal leads. I've studied the book and would have to say that C would be the correct answer,,, What do you think ?
If you want to calculate quantity of thermal energy, then multiply mass, the specific heat capacity (for liquid water this is 4.19J/g degrees Celsius), and the change in temperature.
