It has been found that ‘pyrex’ cookware made of borosilicate glass does not shatter during baking or cooking around 300°F. However, shattering of cookware made of soda-lime-silicate glass was frequently reported during the years 2012-2013. Find and explain the possible reasons for cookware shattering. Show your calculation. Assume that the cookwares are free of pores, cracks, and scratches

The major difference between solid and fluid is the molecules are well-packed in solid but free to move in fluid. As a consequence of such difference, which of the following statements are correct? (i) Stress is proportional to strain in solid but stress is proportional to rate of strain in fluid. (ii) Fluid can be used as a lubricating film to separate 2 solid surfaces from direct contact to reduce friction. (iii) The energy required to move a ship slowly is low but increases rapidly with speed. (A) (B) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above

A sample of lead has a mass of 31.00 kg and a density of 1.130 x104 kg/m3 at 0°C. (Assume the average linear expansion coefficient for lead is  2.900 x10-5(°C−1).) What is the density of lead at 95.00°C? (Give your answer to four significant figures.)
