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

Answer:

Explanation:

Given

Weight of Empty container $W=16\ N$

thus mass of empty container $m_0=\frac{W}{g}=\frac{16}{10}=1.6\ kg$

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 $V=\frac{m}{\rho }$

$V=\frac{34.4}{1000}=0.0344\ m^3$
