Homework Statement
Consider the apparatus that Joule used in his experiments on the mechanical equivalent of heat, shown in the figure below. Suppose both blocks have a mass of 0.69 kg and that they fall through a distance of 0.45 m.
Homework Equations
(a) Find the expected rise in temperature of the water given that 6200 J are needed for every 1.0° C increase. Give your answer in Celsius degrees.
(b) Find the rise in temperature in Fahrenheit degrees.
The Attempt at a Solution
a) Work=2blocks (mgh) = 6.086J
Change in temp= W(1 celsius/6200J)= 9.82e-3
b) I tried converting 1 celsius to fahrenheit so my equation was:
Change in temp= W(33.8/6200J) = 0.033 F but that isn't correct.
I don't know how to do this part of the problem. Any and all help is appreciated
