Chapter 1, Problem 15QAP
Gallium is one of the few metals that can melt at room temperature. Its melting point is 29.76°C. If you leave solid gallium in your car on an early summer morning when the temperature is 75.0°F, what physical state is the gallium in when you return to your car and the interior car temperature is 85.0°F?

In one box of nails, there are 75 iron nails weighing 0.280 lblb . The density of iron is 7.86 g/cm3g/cm3. The specific heat of iron is 0.452 J/g∘CJ/g∘C. The melting point of iron is 1535 ∘C∘C.
Nails made of iron have a density of 7.86 g/cm3g/cm3.
A) What is the volume, in cubic centimeters, of the iron nails in the box?
B) If 40 nails are added to a graduated cylinder containing 15.7 mLmL of water, what is the new level of water, in milliliters, in the cylinder?
A chemist mixes two liquids, A and B, to form a homogeneous mixture. The densities of the liquids are
2.0514 g/mL for A and 2.6678 g/mL for B. When she drops a small object into the mixture, she finds that
the object becomes suspended in the liquid; that is, it neither sinks nor floats. If the mixture is made of
41.37 percent A and 58.63 percent B by volume, what is the density of the metal? Group of answer
choices 2.413 g/mL 1.753 g/mL 2.691 g/mL 2.015 g/mL 1.913 g/mL
Expressing amounts of energy in different energy units is necessary to solve many chemistry problems. For practice,
complete the following table.
The Joule (J) is the SI unit of energy.
The calorie (cal) is the amount of energy needed to raise the temperature of 1 g of water by 1°C. 1 cal = 4.184 J
The British Thermal Unit (BTU) is the amount of energy needed to raise the temperature of 1 pound of water by 1°F.
1 BTU = 1055 J
