What is specific heat? What is its units?
The amount of heat required to raise the temperature of one gram of the substance by one degrees Celsius
Units of J/(g·°C) OR calories/(g·°C)
A solid object with a mass of 67.8g is placed into 174.5 mL of water, and the system reaches thermal equilibrium at 67 degrees Celsius. The solid object is initially at 832.3 degrees Celsius, and the water is initially at 47.3 degrees Celsius.
What is the specific heat of the solid?
0.28 J/(g·°C)
What is the heat equation? Label the variables.
q=CmΔT
q=heat
c=specific heat in J/(g·°C)
m=mass in grams
ΔT= change in temperature (Final temp minus Initial temp) in Celsius
A 313.1 g piece of rhodium at 645.3 °C is dropped in a beaker that contains 754.4 mL of water. The system comes to thermal equilibrium at 47.4 °C. If the specific heat capacity of water is 4.184 J/(g·°C), and the specific heat capacity of rhodium is 0.2428 J/(g·°C), what was the original temperature of the water?
33.0 °C
