Determine the Specifit heat capacity of an alloy that requires 13 kJ of heat energy to raise the temperature of 23 g of alloy from 25 degrees Celsius to 108 degrees Celsius.

9. Calculate the quantity of heat in kJ, associated with a 33.5°C decrease in temperature in a 5.85 kg aluminum bar (specific heat of aluminum=0.903 J g °C•!)

It takes 15.5 kJ of energy to raise the temperature of 2.67 mol of substance from 25.0°C to 70.0°C. What is the molar heat capacity of the substance?

If 226 x 10^3 J of heat increases the temperature of 47.0 kg of copper (Atomic mass = 63.55 g/mole) by 12.5°C, determine is the molar heat capacity of copper?

Exactly 312.4 J will raise the temperature of 15.0 g of a metal from 25.0°C to 60.0°C. What is the specific heat capacity of the metal?

Calculate the energy required to heat 0.30kg of graphite from −4.8°C to 13.1°C . Assume the specific heat capacity of graphite under these conditions is 0.710J·g−1K−1 . Be sure your answer has the correct number of significant digits.

The reaction below is a  exothermic or endothermic reaction. 2SO3(g) + Heat ⇋ 2SO2(g) + O2(g)
