A cooler is a closed container in the shape of a cube, each side 0.5 m in length, and made of polystyrene foam with a thermal conductivity k = 0.010 W /m K. The foam is 5 millimeters thick on all sides. The cooler contains 40 kg of ice and the inside temperature is a constant 0◦C. If the temperature outside the cooler is a constant 25◦C, calculate the power P and the total energy Q conducted through the cooler...
A Styrofoam cooler has a surface area of 2,700 cm2 and a wall thickness of 3.00 cm. Styrofoam has a coefficient of thermal conductivity of 0.010 W/m °C. A 2.00 kg block of ice is placed inside the cooler that has a temperature inside of 2°C. When the temperature outside is 30.0°C, the ice lasts for 8.00 hours. If the temperature outside becomes 20.0°C, then how long will the ice last?
