What are the four states of matter and how might we see them in a crime scene
rodikova [14]
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.

Putting them into a crime scene, however, is tricky.

Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.

Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.

Hoping I helped, and I'd love to receive brainliest answer! :)

Which of the following statements is true? Sweating is an example of postive feedback. Shivering is an example of negative feedb
Alexandra [31]

Answer:

all of the above

Explanation:

All the statements are true that is Sweating is an example of positive feedback because when you sweat your body becomes hot and your inner body becomes cool.  Shivering is an example of negative feedback because shivering occurs when there is cold in the body and can lead to sickness. The nervous system is responsible for sensing changes in the environment because it is responsible for sensing what's going on in our body.

Which of the following samples will have the greatest volume at STP?a. 22 g Neb. 22 g Hec. 22 g O2d. 22 g Cl2 e. All have the sa
sammy [17]

Answer:

22g of He

Explanation:

Volume of gas at STP is given as :

Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹

In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.

Number of moles = \frac{mass }{Molar mass}

Now, let us obtain the molar mass of the given atoms and elements:

For Ne; molar mass is the atomic mass = 20gmol⁻¹

      He = 4gmol⁻¹

      O₂ = (16 x2)gmol⁻¹  = 32gmol⁻¹

      Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹

Number of moles of Ne = \frac{22}{20} = 1.1mol

Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³

       

Number of moles of He = \frac{22}{4} = 5.5mol

Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³

Number of moles of O₂ = \frac{22}{32}  = 0.688mol

Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol

Number of moles of Cl₂ = \frac{22}{71} = 0.3099mol

Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³
