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 a stream 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 latent heat of melting of ice is 0.34 x106 Jkg-1. How long will it take to completely melt the ice block?

c.

Using the Thermal Shock Resistance equation explain what mechanical and physical properties would contribute to increased thermal shock resistance, and why silica is good at resisting thermal shock.

d.

Define convection.

e.

State the equation for the Rayleigh Number, defining all of the terms.

Heat Capacity Learning Goal: To understand the concepts of heat capacity, specific heat, and molar heat capacity. Heat capacity, C, is the amount of energy required to raise the temperature of a substance by exactly 1 degree Celsius. The energy needed to warm an object increases as the mass of that object increases. We see this in our everyday life. For example, we know that it takes much more energy to heat a large tank of water than a small...

An ice “calorimeter” can be used to determine the specific heat capacity of a metal. A piece of hot metal is dropped onto a weighed quantity of ice. The energy transferred from the metal to the ice can be determined from the amount of ice melted. Suppose you heat a 9.36-g piece of platinum to 98.6 °C in a boiling water bath and then drop it onto ice at 0.0 °C. When the temperature of the metal...
