Question

Scientists have for years now studied the behaviour of heat and electricity. Lavoisier argues that heat is an invisible fluid and called it a caloric fluid as it would move from a hotter region to a colder region. He also argued that combustion could not take place without the presence of oxygen gas. Count Rutherford stated that borring out cannons from brass cylinders continually produced heat. The heat could boil water with the original brass maintaining its weight. James Joules’ also revealed that one could generate heat by moving a wire through a magnetic field.

Among the statements below, which one refutes Lavoisier’s idea that heat is a fluid that travels from a hotter substance to a colder one?

Answers

"Lavoisier demonstrated that oxygen was required for combustion."
"He also found the brass filings produced from the drilling process contained enough heat to boil water while retaining their weight."
"Count Rumford observed that the process of boring out cannons from brass cylinders continuously produced heat."
correct

"James Joule discovered that heat could be produced by moving a wire through a magnetic field."

Explanation

James Joules found out that one could mechanically produce heat by passing a wire through a magnetic field rather than being transferred from a hot substance to a cold one. This assertion supports Lavoisier’s hypothesis that support the conversion of mechanical energy to heat, rather than a fluid.
