Question

A container weighs 16 N when empty. When filled with water at 30°C, the mass of the container and its contents is 36 kg. Find the weight of the water in the container, and its volume in cubic meter.

Answer 1

Step-by-step explanation:

Given

Weight of Empty container
`W=16\ N`

thus mass of empty container
`m_0=(W)/(g)=(16)/(10)=1.6\ kg`

mass of container when filled with water is 36 kg

suppose m is the mass of water at
`30^(\circ)C` then

`m+m_0=36`

`1.6+m=36`

`m=34.4\ kg`

Density of water is
`\rho =1000\ kg/m^3`

therefore its volume is
`V=(m)/(\rho )`

`V=(34.4)/(1000)=0.0344\ m^3`
