The bimetallic strip above is made of aluminum (coefficient of liner expansion= 24 ×10−6 °C−1) and gold (coefficient of liner expansion= 14 ×10−6 °C−1). When this strip is held down at the left end and heated, it will ___________________________ A: bend downward B: bend upward C: remain straight, while stretching its length
Homework Answers
B. bend upward
because al has larger thermal expansion when it is heat the bottom al expands more than top gold , it will bend up
aluminium will expand more having more co-efficient of linear expansion.

Thin strips of brass and copper of equal length are used to construct a bimetallic strip. When the strip is heated, due to the difference in the coefficient of linear expansion of the two metals, the brass strip will have a greater increase in length than the copper strip, causing them to bend into an arc with the brass on the outside of the curve. When the temperature of s by 25.8 C, the angle subtended by the two ends...

A certain aluminum alloy has a coefficient of linear expansion of 2.4 ✕ 10−5°C−1. A container made of this alloy has an internal volume of 2.000 L and a depth of 24.5 cm. It is filled to the top with kerosene, which has an average coefficient of volume expansion of 9.90 ✕ 10−4°C−1. Initially the temperature is 25.0°C, and the entire system is slowly warmed until both the cylinder and kerosene are at 89.0°C. (a) How much kerosene overflows? (Enter...
