The beaker which consists of water at a temperature of 45℃ represents ‘The average kinetic energy of water particles’.
<u>Explanation:
</u>
According to ‘Kinetic Molecular Theory of water’ the average kinetic energy of atoms in a system is directly proportional to its temperature. So, this explains that the kinetic energy in between the inner particles of water which is in the beaker is something which represents the temperature of the water as 45℃. This kinetic energy is produced due to the moment of particles of the matter. (A liquid is the second state of matter which is prepared by tiny particles, such as atoms, inter-molecular bonds between the particles helps these atoms to hold together)

Answer: Asteroids, meteoroids, and comets are remnants of the early solar system. This Statement is TRUE.
Explanation:
METEOROID: these are small rocky or metallic objects found in outer space.
ASTEROIDS: these are also known as minor planets of the inner solar system. They are irregularly shaped object in space that orbits the Sun.
COMETS: these are dusty chunk of ice, that moves in a highly elliptical orbit about the sun.
Asteroids, meteoroids, and comets as remnants of the early solar system was further proved in nebular hypothesis
initially proposed in the eighteenth century by German philosopher Immanuel Kant and French mathematician Pierre-Simon Laplace. (The word nebula means a gaseous cloud.) According to the modern version of the theory, about 4.5 to 5 billion years ago the solar system developed out of a huge cloud of gases and dust floating through space. These materials were at first very thin and highly dispersed.
Answer:
they are related because..
Explanation:
Physical properties can be observed or measured without changing the composition of matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others
Answer:
10kg
Explanation:
(I'm not super familiar with the GRESA method so apologies for any inaccuracies)
Given: We are given values for Force: 100N, and Acceleration: 10m/s2.
Required: We are trying to find Mass (m)
Equation: The best equation to use to solve this problem is F=ma,
Force = Mass x Acceleration. We can rearrange this for mass: m = F/a.
Solution: By substituting in the values we have:
Answer: Mass = 10kg
Hope this helped!
Following are the physical properties of the given conditions:
- Copper wire is used to transfer electricity. This property is called Electrical Conductivity. It is defined as the property of material to conduct electricity. Copper is considered as the best conductive material.
- There are 19.3 grams of gold in one cubic centimeter. This statement describes the Density of gold. (Density= mass/volume) Density of material represent mass of material per unit of its volume.
- Iron turns to liquids at 1,534.85°C. That is the given temperature is Melting Point of iron. Melting point is the temperature where a solid starts turning into liquid.
- Silver is very easy to bend. This is called Flexibility of material. Flexibility is the ability of material to deform.
- Fluorite is a green crystal. This shows the color and structure of Fluorite. Green shows the color of material. Whereas crystal is the type of structure the material possess.
