Density = mass/volume
D = 500 g /200 cm^3
D = 2.5 g/cm^3
hope this helps!
Answer:
The electrons are found on the atomic nucleus.
Explanation:
Answer:
B. particles in an object move faster
Explanation:
At higher temperatures, particles in an object moves faster.
Temperature is the degree of hotness or coldness of a body.
- At higher temperature, the substance is very hot.
- Temperature is related to the heat energy content of a body
- As the temperature increases, the average kinetic energy of the particles of system increases more and more.
- This is in compliance with the kinetic molecular theory of matter.
- Therefore, at higher temperatures, particles in an object move faster.
Answer: Option (d) is the correct answer.
Explanation:
Thermal energy is defined as the internal energy of an object because of the kinetic energy present within the molecules of the object.
So, when thermal energy is added to an object then kinetic energy within its molecules will also increase. As a result, temperature of the object will also increase due to increase in number of collisions between the molecules.
Therefore, we can conclude that the statement energy that is associated with temperature, describes thermal energy.
