20g of ice are at thermal equilibrium with 200g of water in a thermally isolated vessel. a 60g block of aluminum at 250 c is dropped into the water-ice solution. lf=333 kj/kg for water, specific heat of water=4.2 kj/(kg k) specific heat of aluminum 0.9 kj/(kg.k) a)-what is the final temperature at thermal equilibrium? b)-what is the entropy change of the 20g of ice?

1st Q: 3 , Q 15: 10 is the distance ,

Step-by-step explanation

Q1- p(y=5x+3) Q(y=2x+4)

5x-2x=3x deference

Q15- Using Pythagorean theorem

a^2 + b^2 = c^2

3 + 7 = 10
