type A solutions UNIT "Matter"
EXAM:
2) A regular container has the next measures: l=150cm, w=60 cm, h=35 cm.
Volume in cm3 ? Capacity in litres?
v=l*w*h= 150*60*h=315,000cm3 1l=1dm3=1000cm3 -->315,000cm3 =315 dm3= 315 l
3)Density of a substance, mass=1,500 kg and volume=15 m3
d=m/v=1500/15=100 kg/m3
4)Convert these temperatures:
-80ºC to K --> K=ºC+273--> K=(-80)+273=193K
160K to ºC-->ºC=K-273 -->ºC=160-273=-113ºC
5) Density of oil is 900kg/m3. There are 9,900,000 g of oil in a container.
Capacity of the container in litres?
9,900,000g=9,900 kg
d=m/v--> v=m/d=9900/900=11m3
1m3=1000dm3=1000l -->11m3= 11,000 l
