Q3a.
Define the specific heat capacity, and state its units.
b.
A Cu bar, 0.5 m long and 1 cm in thickness, is placed in astream of boiling water at one end, and in a 2 kg block of ice at-10°C the other end. The thermal conductivity of Cu is 380 Wm-1K-1,the specific heat capacity of ice is 210 Jkg-1K-1 and the latentheat of melting of ice is 0.34 x106 Jkg-1. How long will it take tocompletely melt the ice block?
c.
Using the Thermal Shock Resistance equation explain whatmechanical and physical properties would contribute to increasedthermal shock resistance, and why silica is good at resistingthermal shock.
d.
Define convection.
e.
State the equation for the Rayleigh Number, defining all of theterms.
