La temperatura de cambio de estado, ¿Puede ser igual para todos los materiales? Justifica comparando dos materiales
Soloha48 [4]

Answer:

No.

Explanation:

Para darnos cuenta de esto tenemos que pensar en lo siguiente:

Pensemos en un vaso de vidrio, lleno de agua hasta la mitad, la otra mitad puede ser manteca derretida

Si metemos el vaso en la heladera durante un par de horas, (sabemos que la manteca en la heladera se mantiene sólida) veremos que la manteca se solidificó en la parte de arriba, mientras que el agua sigue líquida.

Entonces encontramos dos compuestos con distintas temperaturas para cambio de fase, pero materiales es más específico, y puede referirse a materiales puros.

Entonces vamos a dos metales:

Primero tenemos una pieza de hierro y una de mercurio en el congelador (supongamos que ambas están a 0°C).

Ahora los sacamos del congelador y los dejamos llegar a temperatura ambiente.

Como bien sabemos, el mercurio es líquido a temperatura ambiente, entonces el mercurio va a sufrir un cambio de fase

Ahora pensemos en el hierro; claramente va a seguir siendo sólido a temperatura ambiente, entonces podemos ver dos materiales cuyo cambio de fase de sólido a líquido ocurre en distintas temperaturas, por lo que podemos concluir que no, la temperatura de cambio de estado no puede ser igual para todos los materiales, y esto se debe a que la estructura atómica de todos los materiales es diferente.

Pendulum Swing. You pull a simple pendulum that is 0.240 m long to the side through an angle 3.5◦ and release it.
BigorU [14]

The 'period' of a pendulum . . . the time it takes to go back and forth once, and return to where it started . . . is

T = 2π √(length/gravity)

For this pendulum,

T = 2π √(0.24m / 9.8 m/s²)

T = 2π √0.1565 s²

T = 0.983 second

If you pull it to the side and let it go, it hits its highest speed at the BOTTOM of the swing, where all the potential energy you gave it has turned to kinetic energy.  That's 1/4 of the way through a full back-and-forth cycle.

For this pendulum, that'll be (0.983s / 4) =

<em>(A). T = 0.246 second</em>   <em><===</em>

<em></em>

Notice that the formula T = 2π √(length/gravity) doesn't say anything about how far the pendulum is swinging.  For small angles, it doesn't make any difference how far you pull it before you let it go . . . the period will be the same for tiny swings, little swings, and small swings.  It doesn't change if you don't pull it away too far.  So . . .

<em>(B).</em>  The period is the same whether you pulled it 3.5 or 1.75 . <em>T = 0.246 s.</em>

A block of mass 2. 0 kg, starting from rest, is pushed with a constant force across a horizontal track. The position of the bloc
yan [13]

The magnitude of the change in momentum of the block between zero and 4. 0 seconds is

dp=1.6m/s

<h3>What is the magnitude of the change in momentum of the block between zero and 4. 0 seconds?</h3>

Generally, the equation for the kinematics equation is mathematically given as

x=x+ut+0.5at^2

Therefore

1.6=0+0+0.5*a*1^2

a=0.2m/s^2

In conclusion,  change in momentum

dP=mv-mu

2.0*0.8-0

dp=1.6m/s
