Thermal expansion

Question

When the temperature of a body increases

Easy

A

density and moment of inertia increases
B

density and moment of inertia decreses
C

density decreases and moment of inertia increases
D

density increases and moment of inertia decreases

Solution

Density ρ = Mass / Volume
with rise in temperature volume increases,mass remains unchanged.
Again , I = k .m.r²
where K = constant
m= mass
and r = Linear dimension with rise in temperature r increases
