Which metal expands the most when heated?
I image you are talking about thermal expansion, and not for example elastic expansion or other forms of expansions. If you rise the temperature, thermal expansion is represented by a coefficient for linear expansion and a coefficient for volume expansion (the two are naturally linked) that depends on temperature. At room temperature, for aluminum and steel we have linear (10^-6/°C) volume (10^-6/°C) steel 11-13 33-39 aluminum 23 69 where the coefficients for steel depends on the exact composition. Wood is not single material and different woods have very different characteristics. An increase of temperature causes in wood a much more complex phenomenon with respect to what happens in a metal crystal (it is sufficient to think that at high temperature wood can ignite). Considering only small temperature changes around 20°C however we can define thermal dilatation coefficients. However, since the dilatation is not equal in all the directions (since the material is strongly anisotropic) this coefficient depends on the direction where we measure the expansion (or compression). For oak for example, in the direction along the grain of the wood, where dilatation is maximum, the linear expansion coefficient is 54 10^-6/°C. At the end, for small temperature changes wood expands non uniformly, but generally more than metals. Among metals aluminum expands more than almost all the steel types.
Does copper expand more than Aluminium in response to heat?
Well, honey, when it comes to thermal expansion, copper definitely takes the cake over aluminum. Copper expands about 50% more than aluminum when they both heat up. So, if you're looking for something that really knows how to stretch its limits when things heat up, copper is your go-to.
Is copper or aluminum a better heat conductor?
Copper is a better heat conductor compared to aluminum. Copper has higher thermal conductivity, meaning it can transfer heat more efficiently than aluminum. This is why copper is commonly used in applications that require high heat transfer, such as heat exchangers and cookware.
On a hot day which would stay cool longer copper or aluminum?
Copper would stay cooler longer than aluminum as it has a higher thermal conductivity, meaning it can absorb and transfer heat more effectively. Conversely, aluminum has a lower thermal conductivity and would heat up faster than copper in the same conditions.
Does aluminum or copper conduct the most heat?
Copper conducts heat better than aluminum. This is because copper has a higher thermal conductivity, meaning it can transfer heat more effectively. Copper is commonly used in cooking pots and pans due to its excellent heat conduction properties.
What is the Coefficient of thermal expansion for brass?
assuming it is pure copper and not an alloy, 17(k), 9.3 Co
When a bimetallic bar made of copper and iron strips is heated the bar bends toward the iron strip. The reason for this is?
The copper has a higher thermal expansion coefficient than the iron. The copper wants to get longer relative to the iron so the bar bends away from the iron strip. For example if iron is on top and copper on the bottom the bar bows downward. This seems opposite to your question conclusion
When Copper gets longer from heat - what is this called?
thermal expansion
Does a copper heat sink or an aluminum one with a base made of copper work any better than a pure aluminum one?
The thermal conductivity of copper is higher than that of aluminum, and silver is better than either copper or aluminum.
Which physical properties of copper wire are independent of the amount of matter?
Physical properties of copper wire that are independent of the amount of matter include conductivity, resistivity, melting point, and thermal expansion coefficient. These properties remain constant regardless of the quantity of copper wire present.
What is the coefficient of expansion of copper pipe?
The coefficient of linear expansion for copper is around 16.5 x 10^-6 per degree Celsius. This means that for every degree Celsius increase in temperature, a one-meter length of copper pipe will expand by 16.5 micrometers in length.

Thermal coefficient of Copper?
Copper has a CTE of 16.6 parts per million/degree C (16.6E-6/C)
Does aluminum expand twice as much as cast iron?
Aluminum expands more than cast iron when subjected to heat, but not necessarily twice as much. Expansion rates depend on factors like temperature change and material composition, so it's best to refer to specific values from thermal expansion data tables for accurate comparison.
What metal is a good conductor of thermal energy and electric current?
aluminum, copper,
How do you calculate coefficient of linear expansion of copper?
dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT
What two materials that are considered to be good thermal conductors?
Copper and aluminum are two materials known for their high thermal conductivity. They are often used in applications where efficient heat transfer is required, such as in heat sinks or cooking utensils.
