Answer:
1) 2726.5 J/K 2) decrease 3) 0
Explanation:
1)
change in entropy is given by
here Q=mL where L is the latent heat of vaporization. therefore
2)
since the heat is taken from surroundings, the change in entropy is negative therefore entropy of surrounding will decrease.
3) since there is no heat exchange with universe therefore , Q=0 in this case
