A woman is found dead on a boat floating in the middle of a lake at 4:30am. There is blunt force trauma to her head but no other

discernable damage. She is approximately 30 pounds overweight. She is wearing thermal clothing and a winter jacket, gloves, and hat. Climatological data indicate it was a clear, cold, and windy night with no precipitation. Calculate the time of death based only on a body temperature of 15.6°C (60.8°F)? Now consider the other factors presented. How would each affect this estimation?

Answer:

Dead bodies lose one degree Celsius per hour, which we could deduce that the person died 12 hours ago.

Explanation:

On the other hand, it is very important to take into account that this number of hours is very approximate, since not only does it vary greatly with the environment and the acclimatization of the environment in which the person dies, but also in this specific case, insulating clothing was presented , which made the loss of body heat much more difficult and could easily be more than 12 hours.

The minimum for this particular situation is 12 hours to 24 hours possible postmortem.

Create a comic strip that follows the journey of energy from the sun as it travels through the humpback whale
Arisa [49]

The path of energy flow from the sun to the humpback whale is as follows:

  • Sun---> Plankton ---> Small fishes ---> Humpback whale.

<h3>What is energy?</h3>

Energy is the ability to do work.

The primary source of energy on the earth is the sun.

The energy from the sun is used by producers to produce food on which other organisms depend on.

The energy from the sun gets to the humpback whale through producers such as plankton.

The path of energy flow from the sun to the humpback whale is as follows:

  • Sun---> Plankton ---> Small fishes ---> Humpback whale.

If the system 3H2(g) N2(g) 2NH3(g) is at equilibrium and more N2 is added, a net reaction that consumes some of the added N2 wil
kondor19780726 [428]

Group Starts True

A rightward change in equilibrium.

The concentration of gases = [H2] will decrease, [N2] will increase, [NH3] will increase when the new equilibrium is reached.

Additional heat is produced.

The forward and backward reactions' rates quicken in the new equilibrium.

The equilibrium constant decreases as more heat is released.

the exothermic nature of the process.

The equilibrium constant would not have changed if the temperature had remained constant.
