At what temperature will a solid melt?
jolli1 [7]

<u>Answer</u>:

A solid will melt at the temperature at which the kinetic energy breaks the inter-molecular attractions.

<u>Explanation</u>:

The melting point is the state at which "a substance changes its temperature from a solid to  liquid". At the melting point temperature, there is an equilibrium between the both the solid and the liquid phase. When the solid particle is heated by increasing the temperature the particle in the solid vibrate quickly and it absorbs kinetic energy.

It leads to the breaking of the organisation of particle in between the solid and that leads to the melting of solid. Thus, at the melting point, the kinetic energy breaks the inter-molecular attractions.

The speed of light is around 6.706×10^8 miles per hour. What is the speed of light in units of miles per minute?
Sindrei [870]

<u>Answer:</u> The speed of light in miles per minutes is 1.117\times 10^7miles/min

<u>Explanation:</u>

We are given the speed of light is 6.706\times 10^8miles/hr and we need to convert it into miles/min. So, we use the converion factor:

1 hour = 60 minutes

Converting that quantity into miles/minutes, we get:

(\frac{6.706miles}{1hr})(\frac{1hr}{60min})=\frac{1.117\times 10^7miles}{min}

Hence, the speed of light in miles per minutes is 1.117\times 10^7miles/min
