After an afternoon party, a small cooler full of ice is dumped onto the hot ground and melts. If the cooler contained 7.50 kg of ice and the temperature of the ground was 43.0 °C, calculate the energy that is required to melt all the ice at 0 °C. The heat of fusion for water is 80.0 cal/g.

Answer 1

Q1. Cost = $75000

Q2. Total mass = 0.862 ton

Q3. energy required = 600 kcal

Explanation

Q1. length of field = 0.104 km

length of field = 0.104 km * (1000 m / 1 km)

length of field = 104 m

width of field = 74 m

area = (length of field) * (width of field)

area = (104 m) * (74 m)

area = 7696 m²

Cost = (area) * (price)

Cost = (7696 m²) * ($9.75 / m²)

Cost = $75036
