In friction, the kinetic energy of an object may be turned into the random thermal motion of the molecules making up the object

What will be an ideal response?


Friction works roughly like velcro. The surfaces are "sticky." The forces do
work as the objects move with respect to one another, and the work is transformed into
thermal energy.

A substance has a melting point of 20°C and a heat of fusion of 3.9 x 104 J/kg. The boiling point is 150°C and the heat of vaporization is 7.8 x 104 J/kg at a pressure of 1.0 atm

The specific heats for the solid, liquid, and gaseous phases are 600 J/(kg?K), 1000 J/(kg?K), and 400 J/(kg?K), respectively. The quantity of heat required to raise the temperature of 3.80 kg of the substance from -61°C to 128°C, at a pressure of 1.0 atm, is closest to A) 620 kJ. B) 470 kJ. C) 560 kJ. D) 210 kJ. E) 770 kJ.
