Answer to Question 1

The bourdon tube is an oval metal tube that is curved along its length and forms an almost complete circle. One end of the tube is closed, and the other end is connected to the pressure being tested. When pressure is applied to the open end the tube tends to straighten. This motion moves the gauge needle connected to the bourdon tube.

Answer to Question 2

The absolute temperature should be doubled to double the pressure. 25F + 460 = 485 Rankine 485 R x 2 = 970 Rankine
970 Rankine  460 = 510F
