Errrrr, it has 80.
80 is the correct answer
Answer:
The final temperature of the gas is <em>114.53°C</em>.
Explanation:
Firstly, we calculate the change in internal energy, ΔU from the first law of thermodynamics:
ΔU=Q - W
ΔU = 1180 J - 2020 J = -840 J
Secondly, from the ideal gas law, we calculate the final temperature of the gas, using the change in internal energy:


Then we make the final temperature, T₂, subject of the formula:



Therefore the final temperature of the gas, T₂, is 114.53°C.
Answer:
8.61 min
Explanation:
original mass= 12.65
first half life = 12.65/2 = 6.325
second half life = 6.325/2 = 3.1625
Note : 3.1625 is the closest to the value (3.115) given so we work with it
total time for decay =17.22
therefore two decays = 17.22/2= 8.61

Answer: Plasticity
Explanation: Plasticity is defined as the brain's ability to adapt to changes that may result from damage or birth defects. The adaptation that usually occurs is when affected area of the brain is taken over by healthy functioning cortex.
