The latent heat of fusion of alcohol is 25 kcal/kg and its melting point is -114 o c. it has a specific heat of 0.60 in its liquid state. calculate the energy needed to melt 2.0 kg of solid alcohol at -114 o c and raise it to a temperature of -14 o c.

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?
