In an insulated vessel, 250 g of ice at 0°C is added to 600 g of water at 18°C. How much ice remains when the system reaches equilibrium? Assume the heat of fusion of ice is 79.7 cal/g and its specific heat is 0.5 cal/g°C. The heat of vaporization of water is 540 cal/g and its specific heat is 1 cal/g°C.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
