#### A cubic container of the side 0

###### Physics

A cubic container of the side 0.6m is initially open to the air at 300K. The walls of the cube are made of black glass of thickness 6mm. The cube is then sealed and placed in the large furnace with the temperature set to 650K.
After staying inside the furnace for many hours, the cube is taken out, suspended in the air and allowed to cool down in the nearby lab of ambient air temperature of 300K.
A) (4P) Calculate the initial rate of the cube energy change by radiation right after the cube is taken out of the furnace. For this calculation neglect the change in the surface-area of the cube due to its temperature change.
B) (4P)Calculate the initial rate of the cube energy change by conduction right after the cube is taken out of the furnace. For this calculation neglect the change in the size of the cube due to the temperature change.
C) (2P)What is the volume of the cube just before it is taken out of the furnace?
D) (3P)What is the pressure of the gas just before it is taken out of the furnace? Take into account the volume change of the container. Enter this value into the answer box for this question. State your answer in pascals to the nearest Pa.
