As the thermal energy of matter increases, its particles usually spread out, causing?
thermal expansion.
What else can I help you with?
How does temperature differ from thermal energy and what is the relationship between the two?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. The relationship between temperature and thermal energy is that an increase in temperature usually leads to an increase in thermal energy, as the particles move faster and have more energy.
Way difference between temperature and thermal energy and How are they related?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. They are related in that an increase in temperature usually results in an increase in thermal energy, as more particles are moving faster.
How does the volume and density of a substance change when it is heated?
When a substance is heated, its volume generally increases due to thermal expansion. On the other hand, the density of the substance usually decreases since the same amount of matter now occupies a greater volume.
How is temperature distinct from thermal energy?
Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. Temperature is a specific measurement, usually in degrees Celsius or Fahrenheit, while thermal energy is a more general concept that encompasses the total energy of a substance's particles.
What are two factors that determine an object's thermal energy?
An objects temperature and the number of particles

Indicate whether the rate of dissolving increases or decreases for each of the following. a)heat the solution b)stir the solution c)grind the solution?
a) Increases - Heating the solution usually increases the rate of dissolving because it provides more energy to the particles, causing them to move faster and interact more. b) Increases - Stirring the solution increases the rate of dissolving by ensuring that fresh solvent comes into contact with the solute continuously, promoting a more efficient dissolution process. c) Increases - Grinding the solution usually increases the rate of dissolving by increasing the surface area of the solute particles, allowing for more contact with the solvent and speeding up the dissolution process.
Does Temperature increases or decrease when particles are moving faster on average?
Temperature increases when particles are moving faster on average. This is because temperature is a measure of the average kinetic energy of the particles in a substance. As particles move faster, they have higher kinetic energy, leading to an increase in temperature.
When temperature increases does density increase or decrease?
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt

What is thermal run away in bipolar transistors?
A "thermal runaway" occurs when a transistor is heated to such a point, that the more heat it has, the quicker it will accumulate it. This usually involves leakage current which typically increases with temperature, and which causes more current to flow - which increases the heat buildup in the transistor more, and the cycle continues. This heat buildup rapidly accelerates, and it invariably and quickly (in a matter of seconds or quicker) burns out the transistor as it reaches temperatures it was not meant to safely handle.
What is the relationship density and temperature?
Due to thermal expansion, as temperature increases, density decreases.There is no simple relationship. Usually, but not always, if a substance is heated, it will expand, thus decreasing its density.
Energy transfer by convection is usually restricted to what type of substance?
Energy transfer by convection is usually restricted to fluids, such as air or water. These fluids can transfer heat through the movement of their particles, leading to the transfer of thermal energy.
How does the thermal energy of a system change when work is done on The system?
Usually the "thermal energy" will increase since work ON the system adds energy. Thermal energy is really not the best term though. A much better term in thermodynamics would be ENTHALPY.
