Answer:
Heat required = mass× latent heat Q = 0.15 × 871 ×
Friction stole the book's kinetic energy, and turned it into heat energy ... which blew away in the breeze.
The picture is hard to see but if you still need help message me
Answer:
change in internal energy 3.62*10^5 J kg^{-1}
change in enthalapy 5.07*10^5 J kg^{-1}
change in entropy 382.79 J kg^{-1} K^{-1}
Explanation:
adiabatic constant 
specific heat is given as 
gas constant =287 J⋅kg−1⋅K−1

specific heat at constant volume

change in internal energy 

change in enthalapy 

change in entropy
