A rectangular container measuring 20 cm x 42 cm x 42 cm is filled with water.
(a) What is the volume of the container in cm??
(b) What is the volume of the container in mº?
(c) What is the volume of the container in mL (milli-Liters)?
(d) What is the volume of the container in Liters?
(e) What is the mass of the water in the container in grams?
(f) What is the mass of the water in the container in kilograms?

a) volume in cm³ = 20 × 42 × 42 = 35280 cm³

b) volume in m³ = 0.2 × 0.42 × 0.42 = 0.03528 m³

c) volume in ml³ = 200 × 420 × 420 = 35280000 ml³

d) volume in litres = 0.02 × 0.042 × 0.042 = 0.00003528 l³

e) Density = Mass / Volume

Mass = Volume × density

= 0.00003528 × 1

= 0.00003528 × 1000

= 0.03528 grams

f) Mass in kilo gram = 0.00003528 kg

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.
