Question

there are 4 rods R1,R2,R3,R4 of same dimensions. the temperature of R1 is raised to 500°C that of R2 raised to 250°C, R3 raised to 1000°C and R4 raised to 800°C. which rod will have the maximum linear expansion?
a.R1
b. R2
c.R3
d. R4​

Answer 1

Answer:

c.R3 will have the maximum  linear expansion as linear expansion is directly proportional to tempertaure rise

Explanation:

Answer 2

Answer:

R3

Explanation:

because linear expansion is Directly proportional to the temperature rise
