Alter means change. So when a wave hits a big rock, the rock sheds a tiny bit, creating sand.
hope this helped! Please put this as a brainliest answer
Global warming will cause see levels to rise since a lot of water is stored in ice sheets which will melt. All of the melt water will end up in the ocean causing sea levels to rise.
I hope this helps. Let me know if anything is unclear.
Answer:
Forensic methods and techniques.
Explanation:
Forensic methods and techniques include preparing for the execution of the examination, the examination, the collection of objects and samples, the preparation of evidence for laboratory expert evaluation, the interpretation and reporting of evidence.
The purpose of these techniques is to gather evidence to establish the truth.
The main goals of forensics are the reconstruction of the crime, the identification of the suspects, the determination of the motive of the crime, the arrest of the suspect. Forensics research is based on biology, physics, and chemistry. Forensics is one of the most important categories of criminalistics today.
Answer: The final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Explanation:
It is known that the heat capacity of ethylene is 2.145 J/g K. Hence, for 10 moles of ethylene its mass will be as follows.
No. of moles =
10 mol =
mass = 280.5 g
Now, we know that relation between heat energy, mass and specific heat is as follows.
q =
1329.63 = T - 473
T = 1802.63 K
or, =
=
Thus, we can conclude that the final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
