A 2.63 g sample of a substance suspected of being pure gold is warmed to 72.8 degrees Celsius and submerged into 15.5 g of water initially at 24.5 degrees Celsius. The final temperature of the mixture is 27.0 degrees Celsius. What is the specific heat capacity of the unknown substance? Express your answer using to significant figures.

A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 2.30 kg of water at 35.8 °C. During the reaction 74.9 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 1 is 4.18 J.g •K`1 ▪ Be sure your answer has the correct number of significant digits.

Learning Goal: To understand the concepts of heat capacity, specific heat, and molar heat capacity. Heat capacity, C, is the amount of energy required to raise the temperature of a substance by exactly one degree Celsius. The energy needed to warm an object increases as the mass of that object increases. We see this in our everyday life. For example, we know that it takes much more energy to heat a large tank of water than a small cup. Because of this dependence on mass, experimentally determined heat capacities are always reported in terms of the amount of the substance that is heated. One method is to report how much energy it takes to raise the temperature of one mole of a substance by exactly one degree Celsius. This value is the molar heat capacity, which has the symbol Cp. The molar heat capacity is given in the units J mol- °C-1.A second method is to report how much energy it takes to raise the temperature of one gram of a substance by exactly one degree Celsius. This value is…
