What volume of water at 0 ∘C can a freezer make into ice cubes in 1.5 h , if the coefficient of performance of the cooling unit is 9.0 and the power input is 1.2 kilowatt? Express your answer using two significant figures.

Explanation:

= Density of water = 1000 kg/m³

Mass is given by

Energy used is

The volume of water is

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
