how does altering the temperature affect the buoyancy of the object in a liquid?

The Particle Theory of Matter:

* 1. Matter is made up of tiny particles (Atoms & Molecules)

* 2. Particles of Matter are in constant motion.

* 3. Particles of Matter are held together by very strong electric forces

* 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves.

* 5. Each substance has unique particles that are different from the particles of other substances

* 6. Temperature affects the speed of the particles. The higher the temperature, the faster the speed of the particles.

The particle theory of matter explains the following scientific phenomena:

1. Pure substance are homogeneous (one phase - one unique kind of particle)

2. Physical Changes - Melting, Evaporation, Sublimation, Dissolving.....

3. Characteristic Physical Properties - Density, Viscosity, Electrical & Thermal Conductivity

Endothermic = Heat Gain

Exothermic = Heat Loss

What is viscosity?

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey's viscosity is large compared to other liquids' viscosities. If I fill the same cup with water, for example, the cup will drain much more quickly.

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.

i'm unable to work out how. "coloration" represents what frequencies of sunshine at the instant are not absorbed (and, consequently, meditated) off an merchandise. "Buoyancy" represents the relation between the load of an merchandise, its shape, and the density of a liquid the article is placed in.

Altering the temperature means altering the density of the liquid.

THe density of the liquid matters in calculating the buoyant force of the liquid.

The formula for the buoyant force as a reminder is (force)=(liquid density)(volume displaced)(9.8)
