size of an object highly affect the cooling andheating processes for example to increase the temperature of a small piece of iron less amount of heat is required while a bigger piece requires high amount of heat. similarly a room of 10 by 10 having 10 height becomes cooler by using A.C with in 2 or 3 minutes while a room of 20 by 20 having 10 height requires a long time interval for cooling.

Because the larger object has a comparatively larger surface so the ability to give off heat is bigger.

it affects the heatloss because the larger the container means it has a larger surface area meaning there is more room for the particles to escape

Not necessariliy the size, but the surface area.

Larger surface area means faster heat transfer.
