Practical answers to complex questions

# Do particles affect thermal energy?

## Do particles affect thermal energy?

When the average kinetic energy of its particles increases, the object’s thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases. 2.

How does the number of particles influence thermal energy?

The particles in a substance are moving at many speeds. When more of the particles are moving fast, the substance has a higher temperature and feels warmer. When more of the particles are moving slowly, the substance has a lower temperature and feels cooler.

### What factors does thermal energy depend on?

The thermal energy of an object depends on its temperature and mass. The higher the temperature of a substance, the more thermal energy it has. For the same temperature, a substance with a higher mass will also have more thermal energy.

What does thermal energy not depend on?

It will increase because increasing an object’s temperature increases its thermal energy. It won’t change because an object’s thermal energy does not depend on its temperature.

## Which 3 factors does thermal energy depend?

The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object’s molecules (states of matter).

What 3 things does the thermal energy of an object depend on?

### What are the three factors that affect the amount of thermal energy an object has?

1. Mass of object 2. Temperature of the object 3. Phase (solid, liquid, gas) of the object Thermal Energy Page 8 Thermal Expansion An increase in the volume of a material due to a temperature increase.

How are particles and thermal energy related to each other?

The energy in the thermal store of an object is related to the state of motion of its particles and the number of particles (a higher thermal energy follows from a larger number of faster moving particles). Thermal energy is an extensive quantity since it depends upon the number of particles (or mass of substance) present.

## How does the thermal energy of an object depend?

The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object’s molecules (states of matter). The more molecules an object has at a given temperature, the more thermal energy it has. Where do we find thermal energy?

How is the temperature of an object related to its state of motion?

The temperature of an object is related to the state of motion of its particles (the higher the temperature the faster moving are the particles). Temperature is termed an intensive quality since it does not depend upon the number of particles (or mass of substance) present.

### How does the effect of temperature on mass?

Subsequently, question is, does temperature depend on mass? Increasing temperature increases vapor pressure, which speeds up outgassing and evaporation, both of which reduce the mass of the object of interest (while increasing the mass of the atmosphere). Of course, even the statement that temperature has no effect on mass is not strictly true.
