<em>The </em><em>heat </em><em>capacity</em><em> </em><em>of </em><em>a </em><em>body </em><em>is </em><em>defined</em><em> </em><em>as </em><em>the </em><em>heat </em><em>required</em><em> </em><em>to </em><em>raise </em><em>it's </em><em>temperature</em><em> </em><em>by </em><em>me </em><em>degree </em><em>or </em><em>one </em><em>kelvin.</em><em>w</em><em>h</em><em>i</em><em>l</em><em>e</em><em> </em><em>specific</em><em> </em><em>heat </em><em>capacity </em><em>of </em><em>a </em><em>substance</em><em> </em><em>is </em><em>defined</em><em> </em><em>as </em><em>the </em><em>heat </em><em>required</em><em> to</em><em> </em><em>the </em><em>temperature</em><em> </em><em>of </em><em>a </em><em>unit </em><em>mass </em><em>of </em><em>it </em><em>through </em><em>one </em><em>degree </em><em>or </em><em>one </em><em>kelvin</em><em>.</em>

1 particles have got forces of attraction between them
2 they vibrate and rotate at a fixed point
3 they gan heat energy in order for them to melt
4 particles are closely packed together
The speed of sound follows the same rules, just like any other speed, if the acceleration is zero.
distance = speed * time
distance = 2m
speed = 333m/s
Solve for time t.
