12. a sample of ethylene glycol, used in car radiators, has a mass of 34.8 g. the car releases, 783 j of heat. the initial temperature of the sample is 22.1 0c. what is the final temperature? the specific heat capacity of ethylene glycol is 2.42 (j/g 0c)

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
