Do the number of particles in an object affect its thermal energy but not its temperature?
TRUE
What are the two things that the thermal energy depends on?
- How fast the particles are moving - The number of particles in a substance
What are two factors that determine an object's thermal energy?
An objects temperature and the number of particles
What happens to an ideal gas in a closed container when temperature rises?
In a container of constant volume, when the gas is heated, thermal energy is converted to kinetic energy. This increase in kinetic energy causes the gas particles to accelerate. This acceleration of particles causes the particles to crash into each other, increasing pressure. Because it is a closed container, the number of particles and the volume the particles take up remain the same.
What is thermal enegry produced by?
There are a number of principles associated with characterizing the phenomenon of thermal energy. They are generally though of being, and considered/evaluated under the heading of, heat transfer or thermodynamics. The most general answer is this: heat goes from where it's hot to where it's not. Obvious. A link is provided to the Wikipedia article on heat and on thermodynamics. Use them. And no, you won't get tricked. Promise.

How is temperature differ from thermal energy?
Thermal Energy is theTOTAL Ek of atoms in a substance.Temperature is the measure of the AVERAGE Ek of the atoms in a substance.Thermal energy: The total amount of kinetic energy contained in all the particles of a substance. The greater the kinetic energy of the particles in the substance, the more thermal energy the substance has. But thermal energy also depends on the number of particles in a substance. The more particles a substance contains, the greater its thermal energy.Temperature vs. Heat :When you think of temperature, you probably think "hot" or "cold." To scientists, temperature is a measure of the average kinetic energy of the particles in a substance. The more kinetic energy the particles have, the higher the temperature of the substance. Unlike thermal energy, however, temperature is not affected by the number of particles the substance contains.(Taken from: Sciencesaurus A Student Handbook Pp. 301-302)
How do atoms in a liquid transfer heat to nearby atoms?
On a molecular scale, thermal energy is the kinetic energy of individual particles. In a liquid, this thermal energy is transferred to nearby atoms by collisions; a high-speed particle in the liquid collides with a lower-speed particle, transferring some kinetic energy from the high-speed particle to the low-speed particle. When this happens with a large number of particles, thermal energy transfer results.
Which particles have more kinetic energy-those in a substance with a high temperature or those in a substance with a low temperature?
The quality of an answer depends in part on the quality of the question. I am guessing that we are comparing for total thermal energy at fixed given temperature, a given number of particles with a larger number of particles. It makes a difference whether the actual particle makeup stays the same. In other words, we are comparing say some number of particles of Teflon with a greater number of particles of Teflon, and NOT some number of particles of Teflon with a greater number of particles of say iron, or salt; or size A particles compared to size B particles. In that case, yes, the more particles of the same kind, the more energy. Thermal energy is proportional to the mass times the absolute temperature times the specific heat, and specific heat depends on the molecular type and arrangement.

Why must the suns rate of fusion gradually rise over billions of years?
Fusion reactions decrease the overall number of particles in the core, causing the core to shrink, converting gravitational potential energy into thermal energy, and increasing the rate of fusion.
Does the number of particles in a gas affect pressure?
Yes, it is normal.
Does the number of particles affect the pressure of a gas?
Yes, it is normal.
How does the number of particles affect the pressure of a gas?
Increased density and temperature.
