Answer:

As the ice cubes get heated, the particles of the ice also start to heat up. This way, through conduction and radiation, the particles start bouncing on one another and the heat transfers. this way, they particles begin to make way for the other, resulting in the solid changing to liquid, because the particles are now farther apart.

Hope this helps

We can say that the area of the figure equals...

5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle

5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²

2 by 2 triangle = 1/2 x 2 x 2 = 2 un²

2 by 5 triangle = 1/2 x 2 x 5 = 5 un²

9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²

area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²

answer: 26.75 un²
