A block of wood has a volume of 64 cm3 and a mass of 46 grams. What is the density of the block?
1 answer:
The correct answer is 0.72 g/cm3
Explanation:
The density of a material depends on both its mass (amount of matter), which is usually provided in grams (g), and its volume (space occupied), which is provided in units such as cubic centimeters cm3. Moreover, to find how dense the material is, take the mass and divide it into the volume. The process for finding the density of the block of wood is shown below:
This means the density is 0.71g/cm3 and this can be rounded to 0.72 g/cm3

Explanation:
Given parameters:
Initial volume V1 = 200cm³
Initial temperature = 60°C
Final temperature = 120°C
Unknown:
Final volume = ?
Solution:
According to Charles law, at constant pressure, the volume of a given mass of gas is directly proportional to temperature.
mathematically;
1 and 2 are the initial and final states
V is the volume and T is the temperature
convert the temperature to kelvin
T1 = 60 + 273 = 333K
T2 = 120 + 273 = 393K
Input the parameters;
final volume is 236cm³
