A 1.5kg- block of ice is initially at a temperature of -3.0C
a) If 6.0×10^5 of heat are added to the ice, what is the final temperature of the system?
b) Find the amount of ice, if any, that remains
c) Suppose the amount of heat added to the ice block is doubled. By what factor must the mass of the ice be increased if the system is to have the same final temperature?
