a) What is the percentage increase in temperature between 0C and 26C when the temperatures are measured in Kelvin? b) What is the difference between these two temperatures when measured in Kelvin? 0) The outlet of a rocket engine has a cylindrical shape. lts diameter is 2.5m when constructed in the factory at 18C. Given a = 8 x 10'6 K'1 for the alloy used, what will its diameter be (in metres} at its operating temperature of 600C ? d) What will the cross-sectional area of the outlet be (in m2) at this temperature
