A calorimeter contains 27.0 mL of water at 14.0 ∘C . When 2.00 g of X (a substance with a molar mass of 77.0 g/mol ) is added, it dissolves via the reaction X(s)+H2O(l)→X(aq) and the temperature of the solution increases to 26.5 ∘C . Calculate the enthalpy change, ΔH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g⋅∘C)], that density of water is 1.00...

Q = Part 2) If the kettle is 100% efficient, with all the supplied power going into heating the water,...
A 1.00 kg copper bar is heated to atmospheric pressure so that its temperature increases from 20 ° C to 50 ° c. The density of copper is 8.92 x 103 kg and the coefficient of volumetric expansion is 4.5 x 10-5 (C0) -1 Determine the change in volume of the copper bar. (Remember that p = m / V)
A copper pipe carries water in a house. We know that copper expands in all directions when heated. If the temperature of the water rises from 18°C to 44°C, does this inside diameter of the pipe shrink, grow, or remain the same size? Explain using sentences and diagrams.
A 750 g block of copper is heated to 250 degrees C. It is placed in a 350 g aluminum vessel that contains 200 g of water at 5.00 degrees C. What is the final temperature of the copper, water, and aluminum vessel? Specific heat of copper = 0.093 cal/g C degrees Specific heat of aluminum = 0.215 cal/g C degrees Specific heat for water = 1.0 cal/g C degrees
