SPECIFIC HEAT OF METALS LAB NAME_________________PD____
PURPOSE: Determine experimental specific heat of three metals from lab measurements, then calculate %error using actual specific heats found on page 533.
DISCUSSION: q=m* T*Cp; Density of water =1g/mL
energy is conserved, so q metal loses = q water gains
mm* Tm * Cpm (x) = mw * Tw * Cpw
PROCEDURE: as described
DATA
Metal mm Tim Tfm mw Tiw Tfw Cpw Cpm(actual)
CALCULATIONS (x)
Metal Tm Tw Cpm(exp) %error(rchem only) calculations
CONCLUSIONS:
1. What was your average % error?
2. What causes error in this lab?
3. Which substance had the highest specific heat?
4. Which substance had the lowest specific heat?
5. Why did the temperature of the water change much less than the metals?
6. Are heat and temperature the same? How do you know?
7. Why is weather more moderate by the ocean?
