Calculate the q for the water in joules c for water is, Ask an Expert

Academics

A metal object of mass 30.6g was heated to 30.0 degrees Celsius and placed into 20.0mL of water at 19.1 degrees Celsius. (density=1.00g/mL). A thermometer was monitored and a temperature of 20.0 degrees Celsius was recorded as the highest temperature for the calorimetric experiment.

a. Calculate the Q for the water in Joules (c for water is 4.184J/g degrees celsius)

b. Determine the Q for the metal in Joules based on your knowledge of conservation of energy. (you cannot use the Q=mcdeltaT equation, because you do not know the c for metal).

c.Based on the Q value found in B, calculate the specific heat of the metal.

d. You instructor informs you that the metal object was made of silver and has a specific heat value of 0.235J/g degrees Celsius. Calculate the percent error.
