Chemistry

3 0

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.

Explain why it is advantageous that water does not evaporate quickly on earth<br><br> PLEASE HELP!!
stich3 [128]

Answer:

When the humidity is 100 percent, the air is saturated with water. Air pressure also affects evaporation. If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor.
