Problem 20E
Section 17.6 Calorimetry
A 65 cm3 block of iron is removed from an 800°C furnace and immediately dropped into 200 mL of 20°C water. What fraction of the water boils away?
ANSWER:
Step 1 of 2
Here we have to find the fraction of water which gets boiled away.
The volume of the iron block is,
The density of iron is,
.
So, the mass of iron block can be calculated as,
.
The mass of water is,
.
The specific heats are,
.
