Reference no: EM13260292

A 50 kg bag of sand ar 25 degree C falls 10 m onto the pavement and comes to an abrupt stop. Neglect any transfer of heat betweeen the sand and the surroundings and assume that the thermal heat capacity of the snad is so large that its temperature is unchanged.

a) What is the dissapative work done on the sand?

b) what is the change of the internal energy of the sand?

c) What is the entropy change associated with this change in U at constant T?
