The length of metal H will increase more than the length of metal G.

The given problem is based on the concept of thermal expansion. When a certain metal is heated, its length increases according to the thermal expansion equation,

$\dfrac{\Delta L}{L}= \alpha \times \Delta T$

Here, $\Delta L$ and $\Delta T$ are the change in length and change in temperature respectively and L is the original length. And $\alpha$ is the thermal expansion coefficient.

Therefore, we see that the larger the coefficient of linear expansion, the more the metal length increases.

Here we have two metals, G on the top of the strip and H on the bottom, and the coefficient of thermal expansion for metal G is less than that of metal H. So this means that as the strip is heated, the length of metal H (on the bottom) will increase more than the length of metal G (on top): and therefore, the strip will bend towards the top (with metal G in the inside of the curve, while metal H on the outside).

Thus, we can conclude that the length of metal H will increase more than the length of metal G.

The strip will bend towards the top

Explanation:

When a certain metal is heated, its length increases according to the equation

$\frac{\Delta L}{L}=\alpha \Delta T$

where

$\Delta L$ is the increase in length

L is the initial length

$\alpha$ is the coefficient of linear expansion

$\Delta T$ is the change in temperature

Therefore, we see that the larger the coefficient of linear expansion, the more the metal length increases.

Here we have two metals, G on the top of the strip and H on the bottom, and the coefficient of thermal expansion for metal G is less than that of metal H, so

$\alpha_G$

This means that as the strip is heated, the length of metal H (on the bottom) will increase more than the length of metal G (on top): and therefore, the strip will bend towards the top (with metal G in the inside of the curve, while metal H on the outside).
