Experiment 25 calorimetry pre lab answers
When a metal at a higher temperature is transferred to water at a lower temperature, heat is inevitably lost to the calorimeter (Figure 25). Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal?Part A.1. The 200-mm test tube also contained some water (besides the metal) that was subsequently added to the calorimeter (in Part A.4). Considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique error? Explain.

Pre-lab Question-1- \(\PageIndex{1A}\) A 248-g piece of copper is dropped into 390 mL of water at 22.6 °C. The final temperature of the water was measured as 39.9 °C. Calculate the initial temperature of the piece of copper. Assume that all heat transfer occurs between the copper and the water. Answer Here’s the best way to solve it. (1) 10 to 30g metal should be transferred into a test tube that's in the beaker in the water. Let it remain for ten minutes and to reach equilibrium. (2) (a)The calculated heat lost b ….

Sep 22, 2021 · Pre-laboratory Assignment: Calorimetry and Hess’s Law. Show your work for all calculations. When 1.104 grams of iron metal are mixed with 26.023 grams of hydrochloric acid in a coffee cup calorimeter, the temperature rises from 25.2 °C to a maximum of 33.5 °C. The reaction that occurs is given below. When a metal at a higher temperature is transferred to water at a lower temperature, heat is inevitably lost to the calorimeter (Figure 25). Will this unmeasured heat loss increase or decrease the calculated value of the specific heat of the metal?
