A 12 g piece of aluminum is at 70°C. It is placed in a beaker filled with 34.8 g water at 15°C. The final temperature of the mixture is 18.8°C.

a. What is the energy gained by the water if the specific heat capacity is 4.18 J/gºC?

b. What is the energy lost by the aluminum if the specific heat capacity is 9 J/gºC?

  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
