The heat capacity of a calorimeter was determined by heating the calorimeter and its contents using an electrical heater. When 1.25 A of electricity at 3.26 V was passed through the heater immersed in 127.5 g of water in the calorimeter for 175 sec, the temperature rose by 1.222 K. Determine the heat capacity of the calorimeter. The heat capacity of water is 75.291J.K-1.mol-1. Hint: q = i x t x V, where q is in J, i is in A, t is in sec, V is in Volts.

Heat Capacity and Calorimetry
A sample of ethanol, C2H5OH, weighing 2.84 g was burned in an
excess of oxygen in a bomb calorimeter. The temperature of the
calorimeter rose from 25C to 33.73C. If the heat capacity of the
calorimeter and contents is 9.63kJ/C, what is the value of q for
burning 1.00 lol of ethanol at constant volume and 25.00C.
Is q equal to U or H?

Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...

decrease. Give two reasons. 9.62. The heating value of a fuel oil is to be measured in a constant-volume bomb calorimeter. The bomb is charged with oxygen and 0.00215 lbm of the fuel and is then sealed and immersed in an insulated container of water. The initial temperature of the system is 77.00°F. The fuel-oxygen mixture is ignited, and the fuel is completely consumed. The combustion products are CO2(g) and H2O(v). The final calorimeter temperature is 89.06°F. The mass of...

When a solid dissolves in water, heat may be evolved or absorbed. The heat of dissolution (dissolving) can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 0.72 g of KOH(s) are dissolved in 110.70 g of water, the temperature of the solution increases from 25.60to 27.23 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.60 J/°C. Based...
