Answer 1

To respond to the question, we need the data provided with the question.

Answer 2

The specific heat of the masses in this experiment of 5 trial for the substance is 1120 J/kg⁰C.

What is specific heat?

The specific heat of a substance is the amount of heat needed, to raised the temperature of the of one gram of substance by unit degree Celsius.

The specific heat capacity of the substance can be given as,

$c=\dfrac{Q}{m\Delta t}$

Here, (m) is the mass of the substance, (Q) is heat energy and $\Delta T$ is the change in temperature.

As the specific heat of the water is and change in water temperature is 8.4 degree Celsius. Thus the heat energy is,

$Q=50\times4.184\times8.4\\Q=1757.28\rm J$

• The specific heat for the first experiment is,

$c_1=\dfrac{1757.28}{50\times8.4}\\c_1=4.184\rm J/g^oC$

• The specific heat for the second experiment is,

$c_2=\dfrac{1757.28}{150\times15.2}\\c_2=0.77\rm J/g^oC$

• The specific heat for the third experiment is,

$c_3=\dfrac{1757.28}{250\times20.8}\\c_3=0.34\rm J/g^oC$

• The specific heat for the forth experiment is,

$c_4=\dfrac{1757.28}{350\times25.4}\\c_4=0.19\rm J/g^oC$

• The specific heat for the fifth experiment is,

$c_5=\dfrac{1757.28}{450\times29.6}\\c_5=0.13\rm J/g^oC$

The average of all the specific heat is,

$c=\dfrac{4.184+0.77+0.34+0.19+0.13}{5}\\c=1120\rm J/kg^oC$

Thus the specific heat of the masses in this experiment of 5 trial for the substance is 1120 J/kg⁰C.
