# Density&Specific Heat Practice ```Density and Specific Heat Practice
1. A block of unknown composition has a density of 2.3
g/mL and measured 2 cm x 1 cm x 4 cm. What is the
weight of the block?
2. A sample has a specific heat of .155 cal/g&deg;C. How
much energy will be required to raise the temperature
of the sample from 20&deg;C to 35&deg;C, if the sample has a
mass of 8g?
3. What will be the final temperature of the sample in
#2 if 50 cal of energy is used with the same initial
temperature?
4. A 12mL sample of a compound has a density of
1.44g/mL. What is the weight of the sample in mg?
5. What is the mass of a sample that is heated to 65&deg;C
from 20&deg;C using 0.359 kcal of energy. The specific
heat of the sample is 2.1 cal/g&deg;C.
6. What is the density of a 10g sample that raises the
water level in a graduated cylinder from 25mL to
48mL when it is immersed in the water?
7. What is the volume of 5.5g sample with a density of
1.5 g/mL and a specific heat of 0.27 cal/g&deg;C?
