Question

A piston-cylinder apparatus has a piston of mass 2kg and diameterof

10cm resting on a body of water 30 cm high atmospheric pressureis
101 kpa, and the temperature of water 50 degrees Celsius. What is
the mass of water in the container.

Answer 1

M =2.33 kg

Step-by-step explanation:

given data:

mass of piston - 2kg

diameter of piston is 10 cm

height of water 30 cm

atmospheric pressure 101 kPa

water temperature = 50°C

Density of water at 50 degree celcius is 988kg/m^3

volume of cylinder is
`V = A * h`

`= \pi r^2 * h`

`= \pi 0.05^2* 0.3`

mass of available in the given container is

`M = V* d`

`= volume * density`

`= \pi 0.05^2* 0.3 * 988`

M =2.33 kg
