Answer:
(A)0.25L
Explanation:
By combination of Boyle's law and Charles law to obtain the general gas equation, we have:
P1V1/T1=P2V2/T2
P1=Inital pressure=1.00 atm
V1=Inital volume=4.91L
T1=Initial temperature=20°C=20+273=293Kelvin
P2=Final pressure=5.2atm
T2=Final temperature=(-196+273K)=77K
V2= final volume=?
by making V2 the subject of the above general gas equation
we have V2=P1V1T2/P2T1
=1×4.91×77/5.2×293
=0.248L
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.
The role of rhinos in the food chain is... <span>White rhinos are grass-grazing animals, while black rhinos are low browsers. They fill similar roles in their ecosystems to other grazers and browsers. Their size means they eat a LOT, and also means that generally only their offspring are preyed on. So, recycling and trampling high-carbon foliage into fertilizer is their main function.
