Distance between gas molecules in the case of:
-Increase in temperature
-Decrease in temperature
-Increase in volume
-Decrease in volume
-Increase in pressure
-Decrease in pressure
Answer:
-Increase in temperature: increase
-Decrease in temperature: decrease
-Increase in volume: increase
-Decrease in volume: decrease
-Increase in pressure: increase
-Decrease in pressure: decrease
Explanation:
-Increase in temperature:
● Molecules gain kinetic energy and move fast thus increasing distance
-Decrease in temperature:
● Kinetic energy of molecules decrease so they have smaller distance
-Increase in volume:
● Molecules have more space to move around so distance increase
-Decrease in volume:
● Less space, molecules collide with each other because of decreased distance thus increasing pressure
-Increase in pressure
● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance
-Decrease in pressure:
● Molecules collide with each other and walls of container less frequently so distance between molecules decrease

Why is the oort cloud important for understanding the formation of the solar system?
The Oort cloud is the proximate source of observed nearly parabolic, so-called 'new' comets entering the planetary region, and is also the presumed source of the long-period comet flux and the majority of Halley-type comets (HTCs).
The oort cloud is important for understanding the formation of the solar system.
What is oort cloud?It is believed to be an important source of comets that can provide valuable information about the conditions and processes that were present in the early solar system.
Here,
The Oort Cloud is important for understanding the formation of the solar system because it is believed to be a reservoir of icy bodies that formed early in the solar system's history. These icy bodies, which include comets, are thought to have played a key role in the early evolution of the solar system by delivering water and other volatile materials to the inner solar system, including the early Earth.
By studying the composition and properties of comets from the Oort Cloud, scientists can gain insights into the formation and evolution of the solar system and learn more about the conditions that were present in the early solar system.

b)The ability to do work and cause change
c)Stored energy or energy of position
d)The same form of energy moving from one place to another
Answer:
a
Explanation:
what happens to kinetic energy as speed doubles and mass doubles
Answer:
If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision....What happen to the kinetic energy of its velocity become double ? The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy becomes 4 times.
Explanation:
Answer: It increases by four times
Explanation: If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision.

Answer:
C. 100 NEWTONS
Explanation:
just my brain being ly = brainly is the name so my brian is being ly
The weight of the stone is 10N.
To find the weight of the stone, we need to know about the gravitational force on any object due to earth.
What is gravitational force?Gravitational force is a attractive force that arises between any two objects. The objects, on the earth surface or near the earth surface, experience the gravitational force of earth. This gravitational force is Known as the weight of the object. How can we calculate the gravitational force or the weight of an object, when it's near the earth surface?When an object is near the earth surface, its weight is mass × gravitational acceleration (g).
So, the weight of the stone= 1kg × 10 m/s²
= 10 N
Thus, we can conclude that the weight of the stone 100 m above a gorge is 10N.

WHAT IS THE VOLUME OF A 5.71 G PLASTIC CUBE THAT HAS A DENSITY OF 1.15 G/CM3
DONT ANSWER i need to find out if it cant float or sink?!
Answer:
p>Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in. In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
