Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
Internal energy= (- heat evolved by the system) + Work done by the system
ΔU = -Q+W
W = - PΔV
P= pressure
ΔV =difference in volume
Given,
V1 = 10 L
V2 = 90 L
∴ΔV = V2-V1 = 90-10 = 80 L
P = 1 atm
∴W = - ( 1× 80)
= -80 kJ
Heat evolved by the system = 90 kJ
∴Δ U= - 90 kJ - 80 kJ
= - 170 kJ
Thus, Internal combustion energy for TNT(Trinitro toluene) is found to be -170 kJ.
NOTE : here work done by the system is considered negative and also heat evolved by the system is taken -Ve.

Answer:
Texture Gradient
Explanation:
Texture Gradient -
It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .
The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .
The three types of texture gradient are-
- perspective ,
- density and
- distortion of texture elements .
Hence , from the given information of the question ,
The correct answer is texture gradient .
