Answer:

Temperature, the average kinetic energy of particles, tells you how warm something is. Thermal energy, the total kinetic energy of the particles, tells you the extent to which a substance or object can transfer heat or make something else warmer. If an object's temperature increases, its thermal energy increases also.

Difference Between Temperature and Thermal Energy

a. Definition

Temperature: The average kinetic energy of the structural elements of a system (atoms, molecules, charged particles) is called temperature.

Thermal energy: The total kinetic energy of the structural elements of a system is called thermal energy.

b. Values

Temperature: The temperature can be positive and negative.

Thermal energy: The thermal energy always has positive values.

c. Units of measurement

Temperature: The temperature is measured in Celsius, Kelvin, and Fahrenheit.

Thermal energy: The thermal energy is measured in Joule and Calorie.

d. Quantitative dependence

Temperature: The temperature does not depend on the quantity of the substance – it is related to the average kinetic energy of the particles.

Thermal energy: The thermal energy depends on the quantity of the substance – it is related to the total kinetic energy of the particles.

2. The temperature on the Kelvin scale is bigger because the number 273 is always added to the Celcius temperature

3. There’s no really direct connection, however:

The thermal energy of the object is the kinetic energy of the individual molecules that make it up. The more fast-moving molecules inside it, the hotter it is.

When a moving object collides with something, some of the kinetic energy of the object turns into thermal energy. Warming something by rubbing it is an example of this.

4. For a thermometer that is liquid confined in a tube, as the temperature increases, the molecules of the liquid move faster, and the liquid expands. The amount of expansion is related to the increase in temperature.

hope it helps you , thank you

How many moles of NO2 are present in 138.01 g
Sophie [7]

Answer:

3.0002 moles

Explanation:

Data Given:

mass of NO₂ = 138.01 g

No. of moles NO₂ = ?

Solution

To find mass of sample mole formula will be used

mole formula

          no. of mole = mass in grams / molar mass

Molar mass of NO₂ = 14 + 2(16)

Molar mass of NO₂ = 14 + 32 = 46 g/mol

Put values in above equation

               no. of mole = 138.01 g / 46 g/mol

               no. of mole = 3.0002 moles

no. of mole of NO₂ = 3.0002 moles

Chemistry omg need help plz I need plz. I real badly at it and try to get better but plz help me
Rufina [12.5K]
We all struggle in some subjects, you do badly when you don't try, and sometimes we try and can't get the answer, I'll help with that. :)

The first answer is CO2(g), CO2 is a gas, and all gas have... 4) No definite shape, no definite volume.

A piece of ice, a block of wood, and a ceramic cup are solids. They have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume.

A liquid takes the shape of what holds it, besides a flat surface, which will just evidently, take the shape of a flat surface. A liquid has a definite volume, because the volume of a liquid is constant because forces of attraction keep the particles loosely together.

Gases attempt to fill a container of any shape or size. Therefore, it has no definite shape.
There are forces of attraction among the particles in all matter, therefore, it has no definite volume.

The second question might become easier with the explanation above. A liquid has a definite volume because the forces of attraction are loosely together! Therefore, it has a definite volume, but it will take the shape of it's container.

This means... Yes! 2) It retains its original volume but changes shape.

This one is easy. To convert one gram of a solid at its normal heating point to a liquid at the same temperature, is the 1) Heat of Vaporization.

Heat of Vaporization is the amount of heat energy required to convert one gram of a substance from a liquid to a gas.

The third question, the molecules for H20, in a solid phase are always in an geometric and arranged pattern.

Most solids are arranged in geometric and arranged patterns, and since H20 is not in its indefinitely shaped liquid phase, it has a definite shape and thus, retains a repeating (geometric) pattern.

(Note- Some solids like wax or rubber do not have an arranged or geometric pattern.)

The “average of a kinetic energy” is defined as the vitality of movement of particles of a framework.

Or in simpler terms, “energy motion”.

So when temperature increases, the average kinetic energy of a molecule(s) 1) increases.
