<h3>What is a heating curve?</h3>
The heating curve is a representation of temperature change for a body with time as shown on cartesian axes.
The point A represents the steady increase in the temperature of the solid. The point B shows the point of fusion, at this point, the solid is transformed into liquid. The point C shows the temperature rise with time as the liquid is heated. The point D shows the process of vaporization which converts the liquid to gas. The point E shows when the substance now exists in the gas phase.
<span> the horizontal velocity would be equal to Vh = sin (40) /60 = 0.74 * 60 = 44 </span> the Vertical velocity would be equal to <span>Vv = cos(40) * 60 =40</span>
Ideally, 576 J because energy is conserved. In the real world, a tiny tiny tiny tiny bit less than 576 J , because we live in a world with friction and air resistance.
