A reaction taking place in a container with a piston-cylinder assembly absorbs 4850. J of heat and has a change in the internal
Maslowich

Answer:

V_f = 16.3 Ltr

Explanation:

As per first law of thermodynamics we know that

heat absorbed = change in internal energy + Work done

so we have

Heat = 4850 J

\Delta U = 1618.5 J

so work done is given as

4850 = 1618.5 + W

W = 3231.5 J

now we know that at constant pressure the work done is given as

W = P\Delta V

3231.5 = P(V_f - V_i)

3231.5 = 5.5 \times 1.01 \times 10^5(V_f - 10.5 \times 10^{-3})

V_f = 16.3 \times 10^{-3} m^3

or we have

V_f = 16.3 Ltr

The wavelength of light mainly affects our perception of
s2008m [1.1K]

Answer:

I would think the answer is color, if the wavelength is within the visible light spectrum. This could be answered in different ways but I'm pretty sure the answer you are looking for is hue/color.
