Temperature and Density Worksheet #1



Temperature and Density Worksheet Name: ___________________ Per:_____

D = m / v

1. When a 36.7g sample of iron is placed in a graduated cylinder containing 20.0mL, the water level rises to 24.7mL. What is the density of iron?

2. The densities of zinc, chromium and iron are 7.89, 7.20 and 7.86 g/cm3, respectively. A metal with a volume of 12.3mL has a mass of 96.7g. What is this metal? Remember that 1 cm3 is the same as 1 mL.

3. The density of carbon tetrachloride is 1.58g/cm3. What is the mass of 200mL of CCl4?

4. A 33.9g sample of lead is placed in a graduated cylinder containing 20.0mL of water. The lead sinks to the bottom. If the density of lead is 11.4g/cm3, what will the final volume read on the graduated cylinder?

5. Because gases have such little densities, gas densities are typically given in g/L instead of the usual g/mL. For example, chlorine gas has a density of 3.17g/L. If you collect 3.5 liters of chlorine, what is the mass of the gas?

6. Water freezes at what temperature in each scale: Fahrenheit (used in US and 2 other countries only), Celsius (used in the rest of the world and in science) and Kelvin (the absolute temperature scale, also used in science and when measuring gasses).

Temperature Conversions

K = (C + 273

(F = 9/5( (C + 32)

Co = 5/9(Fo-32)

7. Make the following temperature conversions using the formulas above.

a. 0° F ________°C

b. 32° F (freezing point) ________°C

c. 70° F (room temperature) ________°C

d. 98.6° F (body temperature) ________° C

e. 100° F ________°C
