Answer:
141C
Explanation:
We need to use the ideal gas law to solve this question. Ideal gas law: PV = nRT
P = pressure = 4.00 atm = 4.00 × 101.325 = 405.3 kPa (pressure needs to be converted to kilopascals)
V = volume = 4.25L
n = number of moles = 0.500
R = gas constant = 8.314 mol/K (found om chemistry data sheet)
T = temperature = ? unknown
Before any other steps are taken, we need to rearrange the the ideal gas law formula to make T the subject.
PV/nR = T
Now we can substitute the values.
(405.3 × 4.25) ÷ (0.500 × 8.314) = 414.3673322107 (answer in kelvin)
Convert 414.3673322107 Kelvin to Celsius.
0C = 273.15K (found on chemistry data sheet)
414.3673322107 - 273.15 = 141.2173322107C
141.2173322107 to nearest C = 141C
The last one is the correct answer
Blood vessels in the ear dilate or constrict to help regulate body temperature.
Out of those rocks basalt would most likely be found on the ocean floor
