Temperature and kinetic energy have a_______relationship.
2 answers:
Answer : Temperature and kinetic energy have a direct relationship.
Explanation :
The relationship between the kinetic energy of a gas particle and the temperature is,
where,
R = Gas constant
= Avogadro's number
T = temperature
From this we conclude that the kinetic energy of a gas molecule is directly proportional to the the temperature of a gas molecule. That means there is a direct relationship between the kinetic energy and the temperature.
Hence, the temperature and kinetic energy have a direct relationship.

The force needed to stretch the steel wire by 1% is 25,140 N.
The given parameters include;
- diameter of the steel, d = 4 mm
- the radius of the wire, r = 2mm = 0.002 m
- original length of the wire, L₁
- final length of the wire, L₂ = 1.01 x L₁ (increase of 1% = 101%)
- extension of the wire e = L₂ - L₁ = 1.01L₁ - L₁ = 0.01L₁
- the Youngs modulus of steel, E = 200 Gpa
The area of the steel wire is calculated as follows;
The force needed to stretch the wire is calculated from Youngs modulus of elasticity given as;
Thus, the force needed to stretch the steel wire by 1% is 25,140 N.
