EXAM:
2. A regular container has the next measures: l:15 m, w:6 m, h:3.5.
Volume in cubic metres? Capacity in litres?
v=l*w*h=15*6*3.5=315m3 1m3=1000dm3 --> 1dm3=1l --> R=315,000 l
3.Density of a substance; mass=114 g, volume=20cm3?
d=m/v=114/20=5.7 g/cm3
4. Convert: -60ºC to K --> k=ºC+273 -->k=(-60)+273=213K
190K to ºC--> ºC=k-273 -->ºC=190-273=-83ºC
5.The density of oil is 0.9g/cm3 . There are 99 kg of oil in a container.
What is the capacity of the container in litres?
99kg=99000g
d=m/v-->v=m/d=99000/0.9=110,000cm3 1l =1 dm3=1000cm3 -->
110,000cm3=110dm3=110 l
