SOLUTION: 1. A rectangular piece of metal measuring 20.3 cm x 70.5 cm x 2.5 cm weighs 48.5 kg. What is the density of metal in g/cc? 2. The density of a blood sample is 1.052 g/cc. What is

Question 626016: 1. A rectangular piece of metal measuring 20.3 cm x 70.5 cm x 2.5 cm weighs 48.5 kg. What is the density of metal in g/cc?
2. The density of a blood sample is 1.052 g/cc. What is the specific gravity of the sample?
3. The coldest temperature recorded on earth was -110 degree Fahrenheit. What is this temperature in degree Celsius? In Kelvin?
4. Calculate the amount of heat in cal. needed to raise the temperature of 30 g of copper from 28 degree Celsius to its melting point of 1083 degree Celsius. Specific heat of Cu = 0.092 cal/g degree Celsius
5. If 150 cal of heat energy is added to 50.0 g of water at 25 degree Celsius, what is the final temperature of the water? Specific heat of water = 1 cal/g degree Celsius

1. A rectangular piece of metal measuring 20.3 cm x 70.5 cm x 2.5 cm weighs 48.5 kg. What is the density of metal in g/cc?
Vol = 20.3*70.5*2.5 = 3577.875 cc
Density = 48500/Vol
Dens =~ 13.56 gm/cc
-------------------------------
2. The density of a blood sample is 1.052 g/cc. What is the specific gravity of the sample?
SG = 1.052
---------------
3. The coldest temperature recorded on earth was -110 degree Fahrenheit. What is this temperature in degree Celsius? In Kelvin?
-110F = (-110 - 32)/1.8 C
=~ -78.9C
-----------
= C + 273K
= 194K
4. Calculate the amount of heat in cal. needed to raise the temperature of 30 g of copper from 28 degree Celsius to its melting point of 1083 degree Celsius. Specific heat of Cu = 0.092 cal/g degree Celsius
5. If 150 cal of heat energy is added to 50.0 g of water at 25 degree Celsius, what is the final temperature of the water? Specific heat of water = 1 cal/g degree Celsius
