Soalan 1: A block of ice has the shape of a parallelepiped with the dimensions indicated in the figure. The block is oriented in such a way that two of its long surface are horizontal. Its surrounded by 20 C air from all sides. Calculate the total heat transfer rate between the ambient air and the ice block, q (w), by estimating heat transfer each face and the ice melting rate. The ice latent heat of melting is 333.4 kJ/kg. 0.3 m 0.3 m 1 m
