A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 2.80 kg of water at 23.5 °C. During the reaction 73.3 kJ of heat flows out of the bath and into the flask. Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J.g K answer to 3 significant digits. Round your

Consider the following cyclic process carried out in two steps on a gas. Step 1: Step 2: 48 J of heat is added to the gas, and 12 J of expansion work is performed. 66 J of heat is removed from the gas as the gas is compressed back to the initial state. Calculate the work for the gas compression in Step 2. J

10 A student heats 84.17 mL of water to 95.27°C using a hot plate. The heated water is added to a calorimeter containing 73.92 mL of cold water. The water temperature in the calorimeter rises from 2.15°C to 37.48°C. The specific heat capacity of water is 4.184 J and the density of water is g. °C 1.00 mL Assuming that heat was transferred from the hot water to the cold water and the calorimeter, determine the heat capacity of the calorimeter. J Heat capacity of calorimeter = °C

A 45.90 g sample of pure copper is heated in a test tube to 99.40°C. The copper sample is then transferred to a calorimeter containing 61.04 g of deionized water. The water temperature in the calorimeter rises from 24.39°C to 29.10°C. The specific heat capacity of copper metal and water are J and 4.184 J 0.387 respectively. g. °C g. °C Assuming that heat was transferred from the copper to the water and the calorimeter, determine the heat capacity of the calorimeter.

A student is attempting to determine the heat capacity of a Styrofoam cup calorimeter by pouring hot water into a Styrofoam cup containing cold water. The student determined the mass of the cold water to be 21.2455 g and its initial temperature to be 20.36 °C. The mass of the hot water was 24.2646 g and its initial temperature as 34.54 °C. The final temperature of the water after mixing was determined to be 24.57°C. The specific heat capacity of the water is 4.184 J/(g•°C). What is the heat capacity of the Styrofoam cup calorimeter? Assume the temperature of the calorimeter is the same temperature as the cold water. 4.184 J/°C 132.5 J/°C
