How many grams of ice at -13°C must be added to 711 grams of water that is initially at a temperature of 87°C to produce water at a final temperature of 10.0°C?
Assume that no heat is lost to the surroundings and that the container has negligible mass. The specific heat of liquid water is 4190 J/kg•C° and of ice is 2050 J/kg•C°. For water the normal melting point is 0.00°C and the heat of fusion is 334 × 103 J/kg. The normal boiling point is 100°C and the heat of vaporization is 2.26 × 106 J/kg.

If grand unified theories are correct, what caused inflation at the end of the GUT era?
A) Gravity was an extremely weak force at this period in time. B) Large amounts of matter and antimatter annihilated at this time. C) There wasn't enough matter present to slow down the expansion at that time. D) The universe was too small and needed to grow quickly. E) An enormous amount of energy was released when the strong force froze out (became distinct) from the GUT force.
