Atoms gain energy as a solid change to a liquid

Atoms gain energy as a solid change to a gas

Explanation:

The change of phase of a substance involves the absorption or release of the energy by the atoms. When a substance in a solid-state is converted into liquid. The energy is absorbed by the atoms of the substance. That is why the metals need to be heated to convert it into liquid. When the substance recover its original phase, the absorbed energy is released When a substance in the liquid state is heated it transforms into the vapor state. The vapors need to be cooled to convert back to the liquid state.

Atoms gain energy as a solid changes to a liguid

Explanation: In the image, we can see how a thing with a defined shape changes into something with an undefined shape, that can be liquid or gas, let's suppose that it is a liquid because it accumulates at the bottom.

Usually, as you heat a solid, it will reach his fusion point, which is the temperature at which the solid start to change his state from solid to liquid.

As the solid increases its temperature, the energy of the atoms increases (because heat is a form of energy).

Then as the solid changes to liquid, atoms gain energy, because their temperature must increase.

In the case of gas, the situation is the same, atoms gain energy as the solid changes to a gas.

Answer from: Quest

we have been given a quadratic function $f(x)=(x-5)^{2} +2$ and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is $[2,\infty)$ .

if we restrict the domain of this function to either $(-\infty,5]$ or $[5,\infty)$ , it will become one to one function.

let us know find its inverse.

$y=(x-5)^{2}+2$

upon interchanging x and y, we get:

$x=(y-5)^{2}+2$

let us now solve this function for y.

$(y-5)^{2}=x-2\\ y-5=\pm \sqrt{x-2}\\ y=5\pm \sqrt{x-2}\\$

hence, the inverse function would be $f^{-1}(x)=5+\sqrt{x-2}$ if we restrict the domain of original function to $[5,\infty)$ and the inverse function would be $f^{-1}(x)=5-\sqrt{x-2}$ if we restrict the domain to $(-\infty,5]$ .

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
