Answer:

Gunshot residue is important to forensic scientists because it can help measure the firing distance of a weapon, or if someone has fired a weapon lately based on what's on their hands. The potential complications of this evidence include it being uncertain if the residue is from another firing. This type of evidence can also be uncertain in a courtroom when firing distance is drawn into question.

A cube of iron (Cp = 0. 450 J/g•°C) with a mass of 55. 8 g is heated from 25. 0°C to 49. 0°C. How much heat is required for this
Ierofanga [76]

The heat required by the cube of iron has been 602.64 J.

The specific heat has been given as the amount of heat required to raise the temperature of 1 gram of substance by 1 degree Celsius.

The heat required has been expressed as:

\rm Heat=mass\;\times\;specific\;heat\;\times\;\Delta \textit T

<h3 /><h3>Computation for the heat required by Iron sample</h3>

The mass of the sample has been given as 55.8 g

The specific heat of tin has been, c_p=0.450\;\rm J/g^\circ C

The change in temperature, (\Delta T) has been:

\Delta T=\text{Final temperature-Initial temperature}\\\Delta T=49^\circ \text C-25^\circ \text C\\\Delta T=24^\circ \text C

Substituting the values for the heat required:

\rm Heat=55.8\;g\;\times\;0.450\;J/g^\circ C\;\times\;24^\circ C\\Heat=602.64\;J

The heat required by the cube of iron has been 602.64 J.
