00:00 Introduction: Heat and Temperature - Exercise (Part 3)
01:11 Questions 21 to 25: Heat and Temperature - Exercise (Part 3): Chapter 23
Que. 21 A glass window is to be fit in an aluminium frame. The temperature on the working day is 40°C and the glass window measures exactly 20 cm x 30 cm. What should be the size of the
aluminium frame so that there is no stress on the glass in winter even if the temperature drops to°C ? Coefficients of linear expansion for glass and aluminum are 9.0 x 10 °c and 24 x 10 °c respectively.
01:06:52 Questions 26 to 30: Heat and Temperature - Exercise (Part 3): Chapter 23
Que. 26 A steel rod of lengthlm rests on a smooth horizontal base. If it is heated from 0°C to 100°c, what is the longitudinal strain developed?
01:43:01 Questions 31 to 34: Heat and Temperature - Exercise (Part 3): Chapter 23
Que. 31 A steel ball initially at a pressure of 1.0 x 10" Pa is heated from 20°c to 120°c keeping its volume constant. Find the pressure inside the ball. Coefficient of linear expansion of stecl 12 x 10 °c and bulk modulus of steel = 1.6 x 10" Nm.
