when the temperature of a fluid  increases the kinetic energy of the molecules increases.

<u>Explanation:</u>

  • when there is a change in liquid temperature then there will be changes in its properties especially in the (KE) kinetic energy of molecules and the density of the fluid.  
  • Due to the addition of the heat kinetic energy of the fluid molecules as it gains the heat, the intermolecular movement increases so there will be in the increased collision between the molecules which results in breaking the intermolecular force.  
  • Whenever the heat is applied to any matters nature is to tend to expand so the fluids also expand which results in the decrease in the density of the liquid.
  • And also due to the increases in the kinetic energy, the speed of the fluid also increases.

Roman mixes 12 liters of 8% acid solution with a 20% acid solution, which results in a 16% acid solution. Find the number of lit
inysia [295]
Let the 8% solution be A, the 20% solution be B and the final solution be C.

C = A + B
C = 12 + B

0.16C = 0.08(12) + 0.2(B)
0.16(12 + B) = 0.96 + 0.2B
0.96 = 0.04B
B = 24 Liters

C = 12 + 24
C = 36 Liters

Calculate the mass in mg of the aspirin tablet that contains 5.0 grains of aspirin . Assume 1 pound contains 7000 grains.
Rzqust [24]

Answer:

323.99 mg

Explanation:

We need to find the mass of the aspirin tablet that contains 5.0 grains of aspirin.

1 pound = 7000 grains

1\ \text{grain}=\dfrac{1}{7000}\ \text{pounds}

5\ \text{grain}=\dfrac{1}{7000}\times 5\ \text{pounds}\\\\=\dfrac{1}{1400}\ \text{pounds}

We know that, 1 pound = 453.592 grams

Also, 1 pound = 453592 mg

\dfrac{1}{1400}\ \text{pounds}=\dfrac{1}{1400}\times 453592\ mg\\\\=323.99\ \text{mg}

Hence, 4 grains of aspirin contains 323.99 mg.
