Answer:
The Temperature is the measure of Average Kinetic Energy of the molecule in the substance.
Temperature and Kinetic Energy of molecules are related by the equation

Where
<E> denotes average kinetic energy
k - Boltzmann constant
T - Temperature of the substance
Explanation:
The energy inside the substance is characterised by translational and vibrational motion.
The molecules in a substance have a range of kinetic energies because they don't all move at the same speed. As a substance absorbs heat the particles move faster so the average kinetic energy and therefore the temperature increases.
As the molecules of a substance vibrate faster their temperature increases.
Thus an increase energy corresponds to an increase in temperature
<E> α T (α denotes proportionality)

Answer:

Explanation:
We have given mass m = 1 kg
Height of the cylinder 
Diameter d=52.5 mm , so radius 
Volume of the cylinder 
We know that density
Answer:
No image will be observed.
Explanation:
Images that are created by mirrors are virtual images. This virtual image can only be seen by an observer. In this case, an infinite number of images or no image will be created here as both will be reflecting their own images. Light will continuously bounce back and forth reflecting the same image.
