Question
If you left equal masses of iron and water out in the sun on a hot day, which one would be
hotter after 15 minutes? Why?
If the same amount of heat is added to 25.0 g sample of each of the metals in the chart below,
which metal will experience the smallest temperature change?
Metal
Calcium
Iron
Silver
Gold
Specific Heat (J/g°C)
0.647
0.449
0.235
0.129
An object that has a mass of 75 g is heated from 50°C to 93°C. If it takes 3000 J for the
temperature change to occur, then what is the specific heat of the object?
