Would the gap in a metal ring increase as it is heated?
Increases If the gap can easily be conceived as a small break in a metal ring, then the expansion of the metal ring may decrease the gap size.
What is the determination of the size of an object?

How can you increase the pressure on an object without increasing the size of the force?
By heating it or compressing it.
Do particles get smaller or bigger when heated?
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.

Particle size would have much to do with it. The smaller the size of the single particle, the larger the difference between surface area (directly heated) to the volume that has to be heated.
What happens to the Eiffel tower when it is heated?

What the relationships between the surface area of an object and the volume as the object increases in size?
They both increase. The rate of increase of the surface area is equivalent to the rate of increase of the volume raised to the power 2/3.
What happens to an object's acceleration as the size of the force acting on the object increases?
F=m.a , a=F/m; acceleration is directly proportional with force. acceleration increase while force increase.
What factors affect the size of a shadow formed on a screen?
The size of the shadows formed changes if the distance between the object and the screen is also changed. If there is an increase in the distance between the screen and the object, the size of the shadow also increases.
