EXAMPLE: What is the molarity of a solution made by dissolving 5.67 g of potassium chloride in enough water to make 100.0 mL of solution? This data gives a relationship between amount of solute and volume of solution: 5.67 g KCl / 100.0 mL. To find molarity we must convert grams KCl to moles KCl and mL solution to L: 5.67 g KCl 1 mol KCl 1000 mL 0.760 mol KCl x x = or 0.760 M KCl 100.0 mL 74.6 g KCl L L

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.

ss7ja [257]

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 .
