CHEM 001A Lecture Notes - Lecture 16: Calorimetry, Sodium Hydroxide, Jmol
Document Summary
Calorimetry : the measurement of quantity of heat transferred during a physical or. Calorimeter : a device used to measure the absorption or release of heat by a chemical process. physical or chemical process. 23. 5 g of al beads are heated to 100. 0 in boiling water. Heat transferred from water to al until the final temp of al beads = Al beads (at 100. 0 ) are placed in a calorimeter containing 130. 0 g of water at. Q water = (130 g h 2 o)(4. 184 j/g )(26. 0 - 23. 0 ) Heat transferred from al beads to water until thermal equilibrium is achieved at. C p, al = (0. 92 j/g )(26. 98 g/mol) = 25 j/mol . 1. 6 x 10 3 j = (23. 5 g al)(c s, al )(26. 0 - 100. 0 ) 25. 0 ml of 1. 0 m hcl in a coffee cup calorimeter has a temperature of 18. 5 .
