Answer:

Explanation:

solid is particles packed up together like a family.

liquid is made out of particles as well but the are a little spaced out like a bunch of friends going home after a busy school day.

A solid changes state because when heat is applied it states changing state into a liquid.

like you freeze an ice cube and when it out on a summer day in a drink it starts melting AKA (A SOLID + HEAT =A LIQUID

Answer:

Explanation:

Solid changes to liquid when heat is applied and the heat reaches melting point of the particular solid. It is at that point that the solid's strong intermolecular forces is weakened .

Answer:

2.38732 rpm

1.22625 rad/s²

163.292°

Explanation:

g = Acceleration due to gravity = 9.81 m/s²

a = Acceleration = $\frac{1}{8}g$

d = Diameter of wheel = 2 m

r = Radius of wheel = $\frac{d}{2}=\frac{2}{2}=1\ m$

v = Speed of elevator = 25 cm/s

Angular speed is given by

$\omega=\frac{v}{r}\\\Rightarrow \omega=\frac{0.25}{1}\\\Rightarrow \omega=0.25\ rad/s=0.25\times \frac{60}{2\pi}\\\Rightarrow \omega=2.38732\ rpm$

The angular speed of the wheel is 2.38732 rpm

Angular acceleration is given by

$\alpha=\frac{a}{r}\\\Rightarrow \alpha=\frac{\frac{1}{8}g}{r}\\\Rightarrow \alpha=\frac{\frac{1}{8}\times 9.81}{1}\\\Rightarrow \alpha=1.22625\ rad/s^2$
