Equation 19.9, for the thermal shock resistance of a material, is valid for relatively low rates of heat transfer. When the rate is high, then, upon cooling of a body, the maximum temperature change allowable without thermal shock, ΔTf, is approximately where σf is the fracture strength. Determine ΔTf for glass, soda-lime. The values for modulus of elasticity, tensile strength, and coefficient of thermal expansion are 69 GPa, 69 MPa, and 9 x 10-6 °C-1 respectively. Enter your answer in accordance to the question statement 111111.111 °C
