Question

47,454.25J of heat is added to 1000 g of ice at -10 ^oC. How much ice melts?

science physics

Answer 1

Answer #1

LET M grams is melted

heat reqd for 1000 grams of ice to come to 0degrees from -10 degrees is 1000*2.09 * 10

and heat required for m grams of ice to melt is M*333.33

these two must added to given heat

47454.25 = 1000 * 2.09 * 10 + M * 333.3

solving this

m = 79.67 grams
