The heating curve of an ice-water mixture that is slowly heated to 125°C contains three sloped and two level portions. What do t
marin [14]

Answer:

Explanation:

Hi there,

To get started, please recall what heating curves are, latent heat, and enthalpy of phase changes (vaporization, fusion).

In a heating curve for ice water, temperature is the dependent variable (y-axis) and heat or time elapsed is independent variable (x-axis). There are three sloped portions. These sloped portions are showing where the <u>mixture is not changing phase, and is in a specific phase.</u> (solid first, then liquid then gas).

The reason is because the addition of more heat in time is causing the temperature to rise, so the mixture is getting "hotter." The temperature is still rising, yet the mixture is still in the current phase (depending on where you are referencing on the curve).

The two leveled portions are the process of melting (first leveled) and boiling (second leveled). The reason they are horizontal is because the addition of heat is not causing temperature to go up. The molecules are in the process of distributing heat in a different form by changing the mixtures entire structure (AKA phase), and so they are flat because the average kinetic energy from heat is being used change phase.

A mountain lion jumps to a height of 3.25 m when leaving the ground at an angle of 43.2°. What is its initial speed (in m/s) as
miss Akunina [59]

Recall that

{v_f}^2={v_i}^2+2a\Delta y

where v_i and v_f are the lion's initial and final vertical velocities, a is its acceleration, and \Delta y is the vertical displacement.

At its maximum height, the lion has 0 vertical velocity, so we have

0={v_i}^2-2gy_{\rm max}

where <em>g</em> is the acceleration due to gravity, 9.80 m/s², and we take the starting position of the lion on the ground to be the origin so that \Delta y=y_{\rm max}-0=y_{\rm max}.

Let <em>v</em> denote the initial speed of the jump. Then

v_i=v\sin(43.2^\circ)=\sqrt{2\left(9.80\dfrac{\rm m}{\mathrm s^2}\right)(3.25\,\mathrm m)}\implies\boxed{v\approx11.7\dfrac{\rm m}{\rm s}}

Two objects form a closed system. One object, which is at 400 K, absorbs 25.0 kJ of heat from the other object,which is at 500 K
Damm [24]

Explanation:

The given data is as follows.

       T_{1} = 400 K,     T_{2} = 500 K,  

\Delta Q = 25 kJ = 25000 J   (as 1 kJ = 1000 J)

Now, we will calculate the change in entropy as follows.

            \Delta S = \frac{\Delta Q}{\Delta T}

Putting the given values into the above formula as follows.

           \Delta S = \frac{\Delta Q}{\Delta T}

                      = \frac{25000 J}{(500 K - 400 K)}      

                      = 250 J/K

Hence, we can conclude that change in entropy is 250 J/K.
