The equation formula:
P V = n R T
1,245 * 2 l = n R * 300 K
n R = 1,245 * 2 : 300 = 8.3
P * 2.5 l = n R * 400 K
P * 2.5 = 8.3 * 400
P = 3,320 : 2.5 = 1328 J
Answer: A ) 1,328 joules.
A.) conduction.
conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Answer: symphathetic, parasymphatetic
Explanation:
The accelerated heartbeat has a opposite action as compared to the slowed heartbeat likewise the symphathetic nervous system has a opposite action that of parasymphatetic system.
The symphathetic nervous system helps the body to perform intense physical activity like in case of fight or flight response. The parasympathetic nervous system relaxes the body and inhibits its functions that require energy.
Acceleration is equivalent to the rate of change of velocity.
Calculate the difference of velocity, and divide by the total time it took for the change to happen.

That is the answer.
