Gas particles can be assumed to travel in a straight line until they collide with an object?

yes, but since there are atoms and molecules in the atmosphere they bounce off of them and go in a different direction.

What charge does an object have if it has more negative particles than positive particles?
negative
Is radiation a measure of the average kineic energy of the particles in an object?
No, radiation is not a measure of the average kinetic energy of particles in an object. Radiation refers to the emission of energy as electromagnetic waves or particles from a source. The energy of radiation can vary depending on the type and source, and it is not directly related to the average kinetic energy of particles in an object.
What kind of charge does an object have if it has more negative particles than positive particles?
Net positive.
Small bits of an object or substance are called?
Particles.
Explain how the motion of particles in an object changes when its temperature increases?
When temperature increases the particles of an object gain more heat energy, therefore move faster colliding with each other more.
Do gas particles travel in a straight line until they collide with an object?
true
What is the energy transfer between particles as they collide within a substance or between two objects in contact called?
Heat: the transfer of energy from the particles of a warmer object to the particles of a cooler object. (Source: Nelson Science and Technology Grade 7 Textbook, page 186.)
How does the temperature of an object change when its molecules collide?
increase
Why does thermal energy always move from an object with lower temperature to an object with higher temperature?
It doesn't. It's the other way round. Particles in the hotter object are vibrating faster than those in the cooler one. When they collide with each other energy is shared, increasing the temperature of the cooler object and decreasing that of the hotter one.
What happens when an unstopable object meets an unmovable object and they collide together?
They cancel each other out
When two object collide their momentum after the collision is explained by?
Newtons law
When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
It causes it to vibrate which causes it to heat up
Does a warm object have more particles than an identical object that is cooler?
No, it doesn't matter. The number of particles determines the mass of an object, not the temperature.
The thermal energy of an object is?
The total kinetic and potential energy of its particles.
What happens to the particles when an object cools?
When an object cools, the particles' kinetic energy transfers back into potential energy, the particles slow down.
What is a brief summary for the section angularity in the Earth science book?
when particles collide with each other and with other object in their path it happens when sediments is transported from its source to where it is deposited. these collision can cause the particles to change size and shape. angular and uneven rocks are when particles that have moved long distances from the source tends to be more rounder and smoother. the farther sediments travel from its source the finer and smoother the particles of sediments become.
What can be assumed about the buoyant force on an object floating in water?
The buoyant force on a floating object is equal to the object's weight out of water.
