A body at given uniform temperature of 300K and internal energy 8x10^6 J is split in two equal halves:
a)Has any heat been exchanged
b)What is the temperature of each half?
c)What is internal energy of each half?
K=Kelvin
To answer these questions, we need to consider the principles of energy conservation and the concept of thermal equilibrium.
a) Has any heat been exchanged?
In this case, since the body is at a uniform temperature and no information is given about any external factors, we can assume that the body is thermally isolated. In a thermally isolated system, no heat is exchanged with the surroundings. Therefore, in this scenario, no heat has been exchanged.
b) What is the temperature of each half?
Since the body is at a uniform temperature of 300K, splitting it into two equal halves will not change the temperature. Therefore, the temperature of each half is also 300K.
c) What is the internal energy of each half?
Since the internal energy of the body is given as 8x10^6 J and the body is split into two equal halves, we can assume that the internal energy is distributed equally between the halves.
To find the internal energy of each half, we divide the total internal energy by 2:
Internal energy of each half = (Total internal energy) / 2
= (8x10^6 J) / 2
= 4x10^6 J
Therefore, the internal energy of each half is 4x10^6 J.
