The second law of thermodynamics states that whenever energy changes occur, DISORDER always increases.
The Second Law of Thermodynamics states that entropy, which represents the disorder or randomness in a system, always increases when energy changes occur. An example would be heat dispersing from a hot drink into the environment.
The Second Law of Thermodynamics states that whenever energy changes occur, entropy always increases. Entropy refers to the degree of disorder or randomness in a system. Thus, the law is essentially asserting that natural processes tend towards chaos or disorder. For example, if we consider a cup of hot coffee left on a table, with time, the heat (energy) from the coffee disperses into the surrounding environment, leading to an increase in entropy. This concept applies universally in closed systems, where energy cannot enter or leave.

Answer: The correct answer is True.
Explanation:
Average kinetic energy of the particles is defined as the average of the kinetic energies of the particles present in a medium. It is the measure of temperature of the medium.
Mathematically,
where,
K = kinetic energy
T = Temperature
As, kinetic energy of the particles is directly proportional to the temperature. Increase in temperature will result in the increase in the kinetic energy and vice-versa.
We are given, that the temperature of the two glasses are same, so the average kinetic energy of the particles will also remain same.
Hence, the correct answer is True.
The statement ‘If two glasses of water are at the same temperature, the average kinetic energy of the particles of water in each glass is the same’ is true. This is because temperature is directly proportional with the kinetic energy of the molecules. If there is no change in temperature, there would not be kinetic movement of the molecules.
Sarai's displacement in meters will be 1800 when it strolls to the right with an average speed of 1.2m/s for 1500 seconds.
Speed is defined as the ratio of the distance moved by the object at a particular time. The unit of speed is measured in the meter per second, miles per hour, etc.
Average velocity is defined as the sum of all the distances traveled by an object to the time taken by the object to cover the total distance.
Given that Sarai strolls to the right with an average speed of 1.2m/s for 1500 seconds.
To calculate the distance traveled by the object convert the velocity formula into the form of the distance formula then solve for the value of distance.
Velocity = Distance / time
1.2 = Distance / 1500
Distance = 1.2 x 1500= 1800 meters
Therefore, Sarai's displacement in meters will be 1800 when it strolls to the right with an average speed of 1.2m/s for 1500 seconds.

Answer:
1800m
Explanation:
rearrange speed= distance/time
to distance=time*speed
1.2*1500=1800
He reasoned that there must be a source of positive charge within the atom to counterbalance the negative charge on the electrons.
