A copper cube with sides of 1.75 cm. and a temperature change of 50 degrees C 2. A brass object in the shape of an octagonal prism. Sides are 2.5 cm, length is 5 cm, temperature change is 40 degrees C 3. An 4-sided aluminum pyramid. Each side of the pyramid is in the shape of an equilateral triangle with sides of 10 cm. The temperature change is 35 degrees C. brass aluminum copper 1. most increase 2. least increase 3. middleHow much heat is conducted in 3.5 hours through a steel plate 1.5 cm thick having an area of 1.9 my, if the temperature of the two sides is kept at 200 degrees C and 670 degrees C respectively? (Heat transfer coefficient k for steel = 45 Watt/m degree C) The heat conducted = MJ Number
