The entropy change of the surroundings is driven by heat flow and the heat flow determines the sign of ΔSsurr. It can be calculated by the following expression:

ΔSsurr = -(ΔH) / T

We calculate as follows:

ΔSsurr = -13200 / 1337 = 9.87 J/ K mol

Hope this answers the question. Have a nice day.

Si tomamos como referencia el recipiente uno y se aplican 5 gramos de tinta y el agua se moviera a una velocidad de 10m/s cual s

tigry1 [53]

Answer:

Kinetic energy = 0.25 J

Explanation:

The question is "If we take container one as a reference and apply 5 grams of ink and the water moves at a speed of 10m / s, what would the kinetic energy of the solution be?"

We have,

Mass of ink, m = 5 grams = 0.005 kg

Speed of water, v = 10 m/s

We need to find the kinetic energy of the solution of water and ink. Kinetic energy is associated with the motion of an object. Its formula is given by :

$K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 0.005\times (10)^2\\\\K=0.25\ J$

So, the kinetic energy of the solution is 0.25 Joules.

A car traveling at 40 ft/sec decelerates at a constant 5 feet per second per second. how many feet does the car travel before co

Tema [17]

This problem is solved by the equation of motion: x = x0 + v0*t + 1/2*a*t^2, Here x0 = 0, v0 = 40ft/sec and a = -5 ft/s^2, we need to solve for t: v = v0 + a*t, solve how long does it take to stop: 0 = v0 + a*t --> a*t = -v0 --> t = -v0/a -- > 40/5 = 8 seconds to stop. In this time, the car travels x = 0 + 40*8 + 0.5*-5*8^2 ft ~ 160 ft. Answer: The car travels 160 ft.
