The hotness of an object is determined by its temperature, which is a measure of the average kinetic energy of the particles within the object. The higher the temperature, the hotter the object will feel.
The color that an object appears to be is determined by the wavelengths of light that are reflected off the object and into our eyes. Different colors correspond to different wavelengths of light that are absorbed or reflected by the object's surface.
An object's gravitational pull is determined by the object's mass.

It is usually determined by math, and by measuring.
An object's momentum is determined by both its mass and velocity. Momentum is calculated by multiplying the object's mass by its velocity. The momentum of an object can be changed by either changing its mass, its velocity, or both.
The weight of an object is determined by volume, density, and gravity.

No. Loudness is not determined by the wave's frequency, but by its amplitude. That's how much the particles of the object move (how large is the displacement).
The temperature of the object is determined by how often the particles vibrate when a wave passes through it. The higher the temperature, the more the particles vibrate.
How much it weighs.
