## anonymous one year ago What was the important new result shown by Joule's experiment involving paddles stirring known quantities of water? A. it takes work to paddle the water B. liquids have a definite volume but no definite shape C. mechanical energy can be used to stir liquids D. the energy transferred by work is equivalent to the energy transferred by heat

It is the last option, since thanks to Joule's experimentation, we have established the subsequent equivalence: ${\text{work = J}} \times {\text{ amount of heat}}$ where J= 4.18 Joules/cal
