The specific heat of copper is 0.385 j/g•°c. which equation would you use to caculate the amount of heat needed to raise the temperature of 0.75 g of aluminum from 7°c to 29°c?

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
