A 1.3- block of ice is initially at a temperature of -3.5. If 6.6×105 of heat are added to the ice, what is the final temperature of the system?

Find the amount of ice, if any, that remains.

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?

how would i go about trying to do this question(s)? help please.

    heat transfer is what the problem is...
    you need the specfic heat of water (how water reacts to the increase of heat) or dw(t)/dh (change of water temp with respect to heat added) etc etc its calorie/gram °C = 4.186 joule/gram °C make sure the units are the same and find out how much ice gets above 32 or 0 degrees depending on the units and melts
