Origin of specific heat of water
« on: April 18, 2013, 02:20:50 PM »
Hi all,

It's well understood that 4.184 J is the amount of energy required to heat 1 g of water from 14.5C to 15.5C. My question is how was the 4.184 number calculated? One can't just "measure" the enery transfer into a beaker of water, so I'm struggling to understand how the specific heat of water was originally calculated.
