Answer:
from fast-moving to slow-moving particles during particle collisions.
Explanation:
The molecules in every substance are constantly in random motion, which is called thermal motion. This means that they continuously move in random directions with random velocities. In particular, their speed depends on the temperature of the substance: the higher the temperature, the higher the average kinetic energy of the particles, the higher their speed.
However, not all particles move with same speed: some of them move faster, some of them move slower.
Since there are many particles, quite often these particles collide with each other: in the collision, energy is transferred from one particle to another.
In conduction, which is one of the 3 methods of heat transfer (the other 2 being conduction and radiation), the heat is transferred via collision between the molecules.
In particular, according to the laws of thermodynamics, energy is always transferred from particles moving faster (which have therefore more energy) to particles moving slower (which have therefore less energy).
So the correct answer is
from fast-moving to slow-moving particles during particle collisions.
To start the control would be import to see how drivers would act with full focus on the road. The subjects should (in order for the only difference to be the phone) is to use the same vehicle same road same weather condition, just obviously one has the phone the other does not. I hope this helps
Answer:
Ос.
The spacing between particles increases.
Heat causes greater particle activity, and the particles
are farther apart.
Answer:
A) 854.46 kPa
Explanation:
P₁ = initial pressure of the gas = 400 kPa
P₂ = final pressure of the gas = ?
T₁ = initial temperature of the gas = 110 K
T₂ = final temperature of the gas = 235 K
Using the equation
Inserting the values
P₂ = 854.46 kPa
Answer:
Mohammed has less kinetic energy than Autumn
Explanation:
The kinetic energy of each student is given by:
where
m is the mass of the student
v is the speed of the student
Let's use the formula above to calculate the kinetic energy of each student:
- Autumn: 
- Mohammed: 
- Lexy: 
- Chiang: 
Therefore, by looking at the numbers, we see that the correct answer is
Mohammed has less kinetic energy than Autumn
