This law is supported by many experiments and observations, including the famous experiment conducted by James Joule in 1843.In this experiment, Joule showed that when work is done on a system (such as when a weight is lifted), the resulting increase in temperature of the system is due to the conversion of work into heat, and not to any loss or gain of heat from the surroundings. The unit for work is therefore the Newton-meter (Nm), which is also called a joule (after James Prescott Joule who did important early work on thermodynamics). Weve got your back.

This discovery has had profound implications for our understanding of the universe. 1 / 1 point 2. The answer is true. Later, when detectors were installed at the slits, it was observed that each photon only passed through one of the slits, which is again a particle behavior, rather than a wave-like behavior.
