A substance's temperature in physics' laws, is directly related to the average kinetic energy of its particles. Because the particles' mass is constant, they must travel faster as the temperature rises.
<h3>What is Kinetic Energy?</h3>
In physics, the kinetic energy of an object is the energy it possesses as a result of its motion. It is defined as the amount of work required to accelerate a body of a given mass from rest to a given speed.
The body retains its kinetic energy, having acquired it during acceleration, until its speed changes.
Kinetic energy is present in an accelerating ball, a walking human, and electromagnetic radiation like light. Another type of kinetic energy is the energy associated with the continuous, random bouncing of atoms or molecules.

One liquid disappears into another liquid
POH=14-pH=14-2.5=11.5
pH=-log[H+]
2.5=-log [H+]
[H+]=10^-5/2
[OH-]=10^(14-5/2)=10^23/2
answer: dispersed from the liquid so cold air can take its place
Answer: 1.67 kg
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed=
= 
(1kJ=1000J)
m= mass of substance = ?
c = specific heat capacity = 
Change in temperature ,
Putting in the values, we get:
(1kg=1000g)
Thus the mass (in kg) of the copper sample is 1.67
